Welding Wisdom for Professionals and Beginners Alike.

To optimize weld settings for an aluminum welding robot, adjust arc start and end parameters. Use a wire size of at least 3/64”. Select suitable shielding gas. Preheat the aluminum…

Solvent effectively removes oils and greases from aluminum before welding. This preliminary cleaning step improves adhesion and weld quality. Solvent degreasing also facilitates paint removal, making it a better option…

Discover practical videos on welding aluminum. Learn TIG welding techniques and essential methods for cleaning base metal. Use the 5356 filler rod for better results. Follow safe practices while working…

Helium improves aluminum welding by increasing heat input and joint penetration. It works well with Direct Current Electrode Negative (DCEN). When used with Alternating Current (AC), it needs higher voltage…

1100 aluminum is ideal for welding soft metals with similar compositions. It has high weathering and chemical resistance. This alloy is an excellent filler alloy because of its great welding…

Burnback in aluminum welding occurs during GMAW. It happens when the arc moves up the wire and sticks to the contact tip. Common causes include poor grounding, wrong tip or…

Holes in aluminum welds occur due to contamination in the weld pool. Common sources of contamination include hydrocarbon paint and oil. During TIG welding, these substances can enter aluminum pores,…

Porosity in aluminum welding arises from hydrogen during the welding process. Molten aluminum can absorb hydrogen, and as it cools and solidifies, trapped hydrogen creates gas pockets. These gas pockets…

Porosity in aluminum welding occurs mainly due to hydrogen gas becoming trapped in the molten weld pool. Key causes include contamination from hydrocarbons, excessive welding heat, turbulence during welding, and…
