    Advancements in Aerospace Welding Techniques: Ensuring Flight Safety and Performance

    Welding has been a crucial process in the aerospace industry ever since the first commercial aircraft were built.

    Aerospace welding, or structural welding as it is also known, involves a number of processes, mostly related to repairing engines and other mechanical components by joining together various plates, sheets, and metallic frames.

    Aerospace welding is both a lucrative and crucial profession — one that requires a high level of KnowHow about new technologies and evolving safety standards. 

    At the same time, a lot has changed since the early days of the airplane.

    Let’s take a closer look at how some of the latest in aerospace welding techniques can go a long way in ensuring the safety and efficiency of modern aircrafts. 

    Laser Beam Welding 

    Laser Beam Welding is one of the most commonly used processes in aerospace welding, as it allows for narrow and deep welds much faster than other techniques.

    LBW can be used on a variety of materials — including stainless steel and titanium, and aluminum alloys. As the aerospace industry evolves and looks for newer materials to improve flight performance, such flexibility makes it a preferable option. 

    At the same time, LBW doesn’t make use of any filler material, ensuring that the aircraft stays lightweight and that welders spend less time on repair and maintenance. 

    Flash Welding 

    Often used in the construction of aircraft wings and fuselages, flash welding is capable of producing extremely strong welds using an electric arc.

    It is time-effective since it does not require special surface preparation and cost-effective since it doesn’t use any shielding gases. At the same time, it can weld aluminum and temperature-resistant alloys effectively.

    In the aerospace industry, where it is used in jet engines and landing gear, among other components, it offers the added advantage of creating an end product as strong as the base material. 

    Friction Stir Welding

    This welding technique offers the aerospace industry a number of benefits over traditional methods like gas welding. In fact, it is often thought to be better for the environment and the industry’s finances. 

    Much like laser beam welding, this process doesn’t require any filler materials, making it more cost-effective. Meanwhile, similar to flash welding, FSW also doesn’t require any shielding gases, further bringing down the costs of fusion welding. 

    It has the added benefit of allowing manufacturers to do away with fasteners between components, which can also reduce the weight of an aircraft. 

    Electron Beam Welding 

    Known for high welding speeds, deep penetration, and precise welds, electron beam welding has become a staple in the aerospace industry.

    One of its greatest benefits is that the electron beam controls heat distribution and minimizes thermal distortion, ensuring that critical aerospace components perform reliably even when faced with high temperatures and pressure.

    At the same time, it is suitable for welding titanium alloys, which are widely used in aircraft for their light weight and strength, even at elevated temperatures.

    Manufacturing downtime costs American companies billions annually. When production lines halt due to gas supply issues, every minute translates to lost revenue, missed deadlines, and frustrated customers. At nexAir, we've spent decades developing solutions that keep manufacturing operations running smoothly.

    The Hidden Costs of Gas-Related Downtime

    When manufacturers calculate downtime costs, they typically focus on labor and lost production. However, gas supply disruptions create cascading effects that multiply these losses:

    • Production rescheduling that disrupts carefully optimized sequences
    • Rush shipping fees to meet customer deadlines despite delays
    • Quality inconsistencies when processes restart after interruptions
    • Overtime costs to catch up after unplanned stoppages
    • Reputation damage when delivery commitments are missed

    For a typical mid-sized manufacturer, each hour of downtime represents $5,000-$10,000 in direct and indirect costs. Our analysis shows that gas-related issues cause 7-12% of total manufacturing downtime - a substantial opportunity for improvement.

    From Reactive to Proactive: The Supply Continuum

    Most facilities follow a predictable pattern in their gas management evolution:

    Stage 1: Reactive Management At this stage, facilities order gas when they notice supplies running low or, worse, after running out. Emergencies are common, and disruptions are accepted as "part of doing business." One automotive parts supplier operating this way experienced 14 production interruptions in a single quarter.

    Stage 2: Calendar-Based Management Facilities advance to scheduled deliveries based on estimated usage. While better than the reactive approach, this method still results in either excess inventory (tying up capital and space) or shortages when usage spikes occur. A plastics manufacturer following this model maintained 40% more cylinder inventory than necessary while still experiencing occasional stockouts.

    Stage 3: Consumption-Based Management Our telemetry systems monitor actual gas consumption, automatically triggering orders based on usage patterns rather than calendar dates. This approach virtually eliminates both stockouts and excess inventory. 

    Stage 4: Integrated Supply Management The most advanced approach connects gas management directly to production planning systems. Upcoming production requirements automatically adjust supply parameters, ensuring resources are precisely aligned with needs. A medical device manufacturer using this approach reports zero gas-related downtime for 27 consecutive months while operating with minimal inventory buffers.

    Our expert KnowHow™ in industrial gas applications allows us to guide customers through this evolution at a pace that makes sense for their operations.

    Customizing Solutions for Maximum Uptime

    Manufacturing environments vary dramatically in their gas requirements and operational constraints. We've developed flexible approaches that address these differences:

    • For high-volume, consistent usage operations, our bulk systems eliminate the cylinder handling that frequently causes supply disruptions. Bulk installations include telemetry monitoring and automated ordering to prevent outages.
    • For variable-demand environments, our microbulk delivery systems provide the benefits of bulk supply with lower volume commitments. These systems reduce handling requirements while maintaining the flexibility needed for changing production schedules.
    • For specialized applications requiring multiple gas types, our gas management programs combine cylinder tracking, usage monitoring, and automated replenishment. This comprehensive approach ensures that specialty gases are always available when needed, regardless of how infrequently they might be used.
    • For multi-site operations, our enterprise supply programs coordinate deliveries and optimize inventory across locations. By treating the organization's gas requirements holistically, we minimize both stockouts and excess inventory across the network.

    This consultative approach ensures that manufacturers receive solutions aligned with their specific operational patterns rather than generic "one-size-fits-all" systems.

    Beyond Traditional Supply: Integrated Services for Total Reliability

    Maximum uptime requires more than just reliable gas delivery. Our integrated services address the full spectrum of gas-related reliability factors:

    Equipment maintenance programs that prevent system failures before they impact production Technical gas specialists who resolve application issues that could otherwise cause production problems Safety training that prevents accidents leading to downtime events Emergency response capabilities that minimize impacts when unexpected events occur Supply chain redundancy that ensures continuity despite regional disruptions

    These services complement our supply solutions to form a comprehensive reliability strategy. By addressing both everyday operations and exceptional circumstances, we help manufacturers Forge Forward with confidence that gas-related disruptions won't derail their production targets.

    Measuring Success: The Results That Matter

    The ultimate measure of any downtime reduction strategy is its impact on production metrics. Our manufacturing customers consistently report significant improvements after implementing our comprehensive gas management solutions:

    Downtime reductions of 85-95% for gas-related issues Inventory cost decreases of 20-30% through optimized supply management Administrative time savings of 5-10 hours weekly through automated ordering and tracking Production schedule adherence improvements of 3-7% due to improved supply reliability

    These performance gains translate directly to bottom-line benefits that typically deliver ROI within months rather than years. More importantly, they allow manufacturers to confidently make delivery commitments, knowing that gas supply issues won't compromise their ability to perform.
