Nickle Alloy Flat Welding Flange UNS S32750 1.4410 Super Duplex F53

Nickle Alloy Flange, also known as a flange rim or flange, is a part that connects pipes to each other at the ends, and it is also used on equipment inlets and outlets for connecting two pieces of equipment, such as a reducer flange. A flange connection or flange joint refers to a detachable connection consisting of a flange, gasket, and bolt, which together form a combined sealing structure.

Welding Process:

• Required Equipment: A set of manual arc welding equipment, one handle-type angle grinder, one electric air hammer, and one straight edge.
• Folding Welding Preparation: 1. Check and adjust the equipment to ensure normal operation; 2. Prepare φ4.0 J402 welding rods, which are preferably dried at 300°C - 350°C for one hour.
• Folding Welding Process: 1. Assemble the cone and the large flange according to the drawing requirements, then divide the large flange into 8 equal parts; 2. Welding due to the thicker flange and larger groove, the use of segmental symmetrical, multi-layer welding is adopted.
• Folding Welding Quality Requirements: The weld strength must at least match the strength of the base material. The weld surface should be flat and smooth, without defects such as burn-through, porosity, welding leaks, slag inclusion, undercutting, or incomplete welding. The weld reinforcement height should be less than 2mm.
• Folding Notes for Attention: 1. When welding the base layer, always use J506 welding rod manual surfacing and welding with a small current. Strictly follow the welding process; 2: After welding each position, use a level to check the deformation of the flange plane; 3: While welding, use the air hammer to strike the weld to eliminate stress.
