The secret to a sound MIG weld is found by combining several mechanical techniques into one fluid welding motion. Welding is mastered through practice and technique. Trial and error is the way we all learn, but you have to understand the basics first.
Excessive heat or too slow of a travel speed can cause the area to enlarge. On thin materials, heat is a bad thing that leads to warping. To help maintain the amount of heat, we weld in small segments and allow for cooling between welds.
Our focus here at TDO is quality over quantity.
We pay great attention to detail and never have too slow of a travel speed, always making sure that our weld bead is no wider than the thinnest part of our base metal.
