Weld metal cooling rate indicator system

摘要: A weld metal cooling rate indication system is provided for a welding mace. The machine has torch which capable of producing bead and speed sensor senses the at travels as selected by an operator. includes device continuously sensing profile temperatures along bead, this including predetermined temperature. Another receives temperature travel information calculating signal represents change range acceptable rates so that can be compared with range. then responsive to comparing indicating whether within, above, or below temperatures. With arrangement operator adjust proper maintained all times increase quality weld.
