Welding inspection, pre-heating, and post-weld heat treatment (PWHT) services across India. A-Star delivers code-compliant heat treatment per ASME Section IX, ASME B31.3, ASME Section VIII, AWS D1.1, and ISO 15614. Heat treatment scope covers induction heating (high-speed, energy-efficient), resistance ceramic-pad heating (versatile field deployment), and furnace heat treatment for shop fabrication — all with calibrated thermocouples, automatic chart recorders, and acceptance-grade output charts. Welding inspection scope includes WPQ / PQR qualification, production weld supervision, PAUT and RT-based weld acceptance per ASME Code Case 2235, and AWS / API code compliance. Pre-heating services support refinery turnarounds, fabrication yards, and on-site industrial welding work where strict temperature control is required to prevent hydrogen-induced cracking and stress corrosion. Personnel hold ASNT Level II/III, CSWIP 3.1/3.2, AWS CWI, and IBR-qualified credentials. Mobilisation from Mumbai, Delhi NCR, Chennai, Hyderabad, Vishakhapatnam, and Jamnagar within 5 working days; urgent within 48 hours. Combined heat treatment + welding inspection contracts simplify procurement and ensure full traceability across the entire welding workflow.
