Stainless Steel Welding Best Practices

Safety and Preparation

Preparation of equipment, materials and the work area is essential before engaging in any kind of welding process suitable for stainless steels. A dedicated stainless steel wire brush to prepare the metals will decrease the chances of contamination. Gloves, goggles and other protective gear will minimise the risk of accidents such as exposure to fumes and injury due to spatter.

Filler Metal Selection

Choosing the appropriate filler material depending on the scope of work is really important. Most of the time it should match the grade of the stainless steel, achieving almost the same properties. Other considerations in choosing filler material include weld joint design, aesthetics and overall weld performance.

Parameters

An experienced welding provider understands the finer details of each stainless steel grade, weldable metals and welding method. It leads to a better choice when fine-tuning the parameters such as the power supply, torch angle, travel speed and deposition rate. Effective use of these welding parameters will help to achieve the highest quality welds.

Shielding Gas

The choice of shielding gas in processes such as MIG andTIG welding is crucial in protecting the weld pool from contamination. The correct shielding gas composition will reduce the risk of weld defects and improve the weld’s overall outcome.

Heat Input

Consider the variables of the welding project in determining the ideal heat input to weld stainless steel. Generally, the welding current should be about 20% less than for carbon steel to Prevent corrosion.
