Too much heat makes the puddle too fluid, causing it to fall out. Too little, and you lack the penetration needed for a structural bond. Line of Sight:
MIG overhead is cleaner but requires precise gun angle. 4f welding position full
The refers to an overhead fillet weld, one of the most challenging positions in welding. It involves joining two pieces of metal—typically a vertical plate and a horizontal plate—to form a T-joint, where the welding is performed from underneath. 1.
