9-POWER STAINLESS STEEL WELDING ELECTRODES
Which electrode is used for SS welding?
Stainless steel is a popular material used in various industries such as construction, automotive, and aerospace due to its high strength and corrosion resistance.
Welding is commonly used to join stainless steel components, and welding electrodes play a crucial role in this process.
This article will discuss the various aspects of stainless steel welding electrodes.
For stainless steel welding, electrodes made of a specific type of stainless steel alloy are used. These electrodes have a coating that shields the weld pool from atmospheric gases and prevents the formation of oxides, which can cause defects in the weld.
Types of Welding Electrodes for Stainless Steel
Various types of welding electrodes for stainless steel are classified according to their composition and coating.
The most common types are:
E308L: This is a low-carbon electrode with a high chromium and nickel content. It is suitable for welding austenitic stainless steels such as 304 and 304L.
E309L: This electrode is designed for welding dissimilar metals such as stainless steel to carbon or low-alloy steel. It has a higher carbon content than E308L and is suitable for welding thicker sections.
E316L: This electrode has a higher molybdenum content than E308L, making it suitable for welding corrosion-resistant austenitic stainless steels such as 316 and 316L.

Welding Positions:PA,PB,PD,PF Attention: 1.Electrode must be approved by 320-350 â?? for 1 hour before welding, dry the electrode when use it. 2. The rust, oil, water and other impurities of the weld must be removed before welding. 3.Recommended DC power supply, because AC welding has a shallow penetration, the current should not be too large, in order to avoid the coating redness and cracking. 4. To minimize the amount of heat input and welding electrode oscillating amplitude shoulds not be too big. 5.Preheat and interlayer-temperature should remain below 150
