In GMAW (gas metal arc welding) practice, horizontal welding is a position that many beginners have mixed feelings about. It’s easier than vertical or overhead welding, but if parameters an...
No matter where the welding joint is, it is actually an accumulation of welding experience. For novices, simple positions are the basic exercises, starting with rotations and moving on to fixed pos...
Welding electrodes are metal wires with baked on chemical coatings. The rod is used to sustain the welding arc and to provide the filler metal required for the joint to be welded. The coating prote...
Spot welding is a resistance welding method in which the weldment is assembled into a lap joint and pressed between two electrodes, and the base metal is melted by resistance heat to form a solder ...
Important structures such as boilers and pressure vessels require safe penetration of joints, but due to limitations in structure size and shape, double-sided welding is sometimes impossible. A sp...
In GMAW (gas metal arc welding) practice, vertical welding is a real challenge for many welders. If you’re not careful, the molten metal drips down, the weld bead looks like a bunch of berr...
