Welding Techniques — Technical & Short
Can you identify the welding technique just by looking at the bead pattern—and explain WHY the welder used it? 1. Stringer Bead Welding Technique: Straight bead, minimum/no transverse weaving. »Why: ↓ Heat input, distortion & sensitization risk; better control. »Process: SMAW / GTAW ...Read more -
WELDING CURRENT MATTERS MORE THAN YOU THINK!
Every quality weld begins with selecting the correct current type, polarity, and control mode. Even with the best welding procedure and skilled welder, an incorrect polarity can result in poor penetration, excessive spatter, lack of fusion, or distortion. ☆Key Takeaways: ♦AC (Alternating Current)...Read more -
Preheating Methods in Welding
Preheating is not just about applying heat before welding. It is a critical metallurgical control that directly impacts weld integrity, hydrogen control, and residual stress management. Below is the widely used preheating methods: 1 Propane Torch Heating Simple, portable, and commonly used in fi...Read more -
4 Main Types of Surfacing in Welding & Repair
Not all welding is about joining two components. In many industries, welding is also used to restore, protect, strengthen, and extend the service life of critical equipment.

Types of Welding
1. Arc Welding (Electric Welding) Uses an electric arc to melt and join metals. Types include: SMAW (Shielded Metal Arc Welding / Stick Welding) GMAW (Gas Metal Arc Welding / MIG Welding) GTAW (Gas Tungsten Arc Welding / TIG Welding) FCAW (Flux-Cored Arc Welding) SAW (Submerged Arc Welding) ̵...Read more -
WELDING SYMBOLS USED IN PRESSURE VESSEL MANUFACTURING
In pressure vessel manufacturing, welding is not only about joining metal plates. Before a welder strikes the arc, the drawing already defines what type of weld to perform, where to apply it, how much to weld, and which process to follow — all through welding symbols. Why Welding Symbols Matter ...Read more -
