Title:
LASER BRAZING SYSTEM WITH A COOLING SECTION ON A WIRE FEEDING TORCH, AND A WATER COOLED WIRE FEED TIP COLLAR
Document Type and Number:
WIPO Patent Application WO/2018/132566
Kind Code:
A8
Abstract:
The present application relates to a laser brazing system (20) including a torch body (24), a wire feed tip (28), a laser processing head (32), and a cooling collar (34). The torch body (24) includes nozzle, mounting, and cooling sections (42, 44, 46). The nozzle section (42) has a nozzle wall (50) and a feed wire conduit (52). The cooling section (44) has a cooling barrel (76), a coolant supply connection (78), and a coolant return connection (80). The wire feed tip (28) has a feed wire outlet (70) and is connected to one end of the torch body (24). The laser processing head (32) directs laser light toward the feed wire outlet (70). The cooling collar (34) is disposed on the nozzle section (42) and includes a collar body (140) and a coolant conduit (142). The collar body (140) has a through-bore (152) that receives the nozzle wall (50). The coolant conduit (142) has an end portion (184) attached to the collar body (140) and a leg portion (186) that transports coolant to and from the end portion (184).
