IPG welding heads can be fitted with a variety of module options for optimized results in specific applications. The Dual-spot Module splits a single spot into two spots with equal powers and a fixed separation. The module is installed between the collimator and the core block modules. When used in line with the welding seam, the Dual Spot module reduces spatter and increases welding speed. The Dual Spot module is also used transverse to the welding seam to improve weld quality and visual finish when the gap tolerance varies.
