Spray applicators are now available that coat welding nozzle surfaces and prevent spatter adherence and nozzle obstructions. This allows shielding gases to flow freely and the wire to feed evenly. Compared to common gel-based products, these applications have been shown to last longer and reduce nozzle replacements, treatment costs, and spatter removal labour costs. Aluminum’s high strength-to-weight ratio has long made it an obvious choice in automotive and aerospace sectors, primarily because it is lightweight and corrosion-resistant. Although aluminum is not the strongest of metals, alloying it with other metals, such as copper, magnesium, tin, and zinc, helps increase its strength, durability, and mass. Aluminum alloys are easily workable but, as with any fabrication material, there are advantages and disadvantages. On one hand, cast aluminum products are relatively low-cost because of aluminum’s low melting point. On the other hand, they have lower tensile strengths. Additionally, aluminum alloys will warp at high temperatures. They have lower fatigue limits than steel and weaken with repeated stress, which is why aluminum alloys are rarely used in high fatigue-tolerance ap...
