UNS N06600 N06601 Nickel Alloy Inconel Cladding Tube Oil Gas Transport Steel Tube

Production Information of Inconel Cladding Tube

Surfacing welding is a welding process in which a layer of wear-resistant, corrosion-resistant and heat-resistant metal layer is deposited on the surface or edge of the workpiece, and the metal is melted by electric welding or gas welding and stacked on the tool or machine parts

The most common problem in surfacing is cracking. The main methods to prevent cracking are as follows

1. Preheat before welding, control interlayer temperature and slow cooling after welding

2. Stress relief heat treatment after welding

3. Avoid multi-layer surfacing and use low hydrogen surfacing electrode

4. If necessary, build up the transition layer between the surfacing layer and the base metal (use the electrode with low carbon equivalent and high toughness)

Attention must be paid to butt welding:

1. According to the use requirements, reasonable selection of surfacing alloy

2. Reduce the dilution ratio of base metal as much as possible

3. Improve productivity

4. It is expected that the hardfacing metal and base metal have similar expansion coefficient and phase transformation temperature

Purpose of surfacing welding of Inconel Cladding Tube :

1. Reduce costs

2. Extend service life

3. Reduce maintenance

4. Reduce spare parts
