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...
Shielded Metal Arc Welding (abbreviated as SMAW). The principle is: an arc is generated between the coated electrode and the base metal, and the welding method using the arc heat to melt the electr...
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...
Welding can use AC or DC welding machine. When using a DC welding machine, there are positive connection and reverse connection. Factors such as the electrode used, the condition of the constructio...
Single-sided welding with double-sided formation is a core technique that welders must master, and it is particularly critical in the welding of pressure vessels and pipelines. It requires the wel...
In the welding process, there are many matters needing attention. Once neglected, it may be a big mistake. These are the points you must pay attention to if auditing the welding process. If you de...
