How to prevent the causes and hazards of welding flash during operation?

【Summary Description】 The liquid metal in the weld flows to the base metal that is not melted under heating or overflows from the root of the weld, and the metal nodules formed after cooling that are not fused with the base metal are the weld nodules. Too strong welding specification, too fast welding rod melting, poor quality of welding rod (such as eccentric core), unstable welding power supply characteristics and improper operation posture are all easy to bring welding flash. In the horizontal, vertical, vertical position is more likely to form a weld bead. The weld flare is often accompanied by incomplete fusion and slag inclusion defects, which can easily lead to cracks. At the same time, the weld bead changes the actual size of the weld, which will bring stress concentration. The internal weld of the pipe reduces its internal diameter and may cause blockage of the flow. Measures to prevent weld flare: make the weld in the flat welding position, correctly select the specification, select the non-biased core electrode, and operate reasonably.
