The metal water pipes in the video are used in the microcomputer heating control cabinet.
The welding of the shunt tube requires the use of the pull welding method and the carbon dioxide gas shielded welding, so that the shunt tube and the main pipe are firmly connected.
For pull welding, the quality standard:
1. The degree of melting reaches 100% (steel current 35-50V, iron current 40-50V).
2. The front and back, left and right of the welding shape are straight and small.
3. No holes, no gaps, no shadow, no deformation, no bubbles.
For carbon dioxide gas shielded welding, there is a protective gas outflow during welding, and the welding position forms an isolated air from the outside to ensure the welding quality. The weld seam of carbon dioxide gas shielded welding has high crack resistance, low weld hydrogen and less nitrogen. The deformation after welding is small, the angular deformation is five thousandths, and the unevenness is only three thousandths.
