WebMar 9, 2024 · The J.H. Bennett Technical Services team designed and built this High Flow Weld Controller to solve our customers inconsistent pressure issue. This system features … Porosity, one of the most common MIG welding defects, is the result of gas becoming trapped in the weld metal. Inadequate shielding gas coverageis among the biggest culprits, and this can be addressed in several ways. First, check the regulator or flow meter for adequate gas flow, increasing it as necessary. … See more The terms cold lap and lack of fusion are often used interchangeably. However, they are slightly different and can happen independently or in conjunction with one another in MIG welding. Lack of fusion is the result of the weld … See more Burn-through, which happens when the weld metal penetrates completely through the base material, is especially common when welding thin materials less than 1/8 inch or about 12 gauge. Excessive heat is the main cause of … See more The goal is to create a smooth, flat weld bead. Welds that are too concave or convex can compromise the integrity of the finished product.
