Relationship between Weld Time and Nugget Size: Weld time is a crucial factor in determining the nugget size in resistance spot welding. Nugget size, the diameter of the fused area where the sheets are joined, is directly proportional to weld time. As weld time increases, the molten metal has more time to expand and form…
GTAW pulsed welding employs a pulsed power supply to deliver a series of short, controlled pulses of electrical current to the welding arc. This advanced technique offers benefits such as reduced distortion, improved weld quality, and enhanced control over heat input. Pulsed GTAW is commonly used in specialized industries like aerospace, automotive, and medical device…
Filler material, also known as welding rod or filler wire, provides additional metal to the weld joint, compensating for the metal lost during the welding process. It comes in various forms, such as rods, wires, and strips, and is crucial in filling gaps, bridging edges, and creating a strong and durable weld. Filler material is…
India’s waste management system involves various key players ensuring environmental protection. The Central Pollution Control Board (CPCB) establishes environmental standards, while State Pollution Control Boards (SPCBs) enforce them.
