The welding quality and Matters of the flange connection
Dec 01, 2017

The weld strength is required to reach at least the strength of the base metal. The welding surface is neat and smooth, no burning, air hole, welding leakage, slag, undercut, incompletely filling and other defects. The reinforcement is less than 2mm.

Matters needing attention of the flange connection

1. Make sure to use the J506 welding rod for manual build-up welding during  priming, and use small current welding. And weld strictly in accordance with the welding process.
2. After welding each position, use a level ruler to check the deformation of the flange plane.
3. Peen the weld seam when welding, so as to eliminate the effect of the stress.
