Weld with precision
A Place That Helps
Growth of Your knowledge
In today’s fast-paced world, it is essential to engage in learning that transcends theoretical concepts and emphasizes real-world application.
CE AND PCM IN WELDING
CE (Carbon Equivalent) and PCM (Composition Parameter) are used to evaluate the weldability and cold-cracking susceptibility of steel.
HEAT INPUT
HEAT input plays an important role in determining the weld's cooling rate, microstructure, and final mechanical properties.
SDSS WELDING
Super Duplex Stainless Steel welding requires precise control over heat input, interpass temperature and shielding gases to maintain a 50/50 balance of ferrite and austenite phases.
SS WELDING
The weldability of stainless steel depends on various factors, including its composition, surface condition, and welding method. Austenitic stainless steels, such as 304 and 316 generally exhibit good weldability.
PREHEATING IN WELDING
Preheating is mainly used to slow down the cooling rate.
