Abstract
A welding (10) for use with gas metal arc welding wherein the welding head (10) has a diffuser body (16) with an inlet end (28) and an outlet end (38). A welding tip (14) is axially located within the diffuser body (16) and extends axially beyond the outlet end (38). The diffuser body (16) has a gas outlet (37) and a gas inlet (34), and there is at least one gas channel (36) operatively connecting the gas inlet (34) and the gas outlet (37). One or more diffusing lenses (20) are provided between the gas outlet (37) and the outlet end (38).
Claims11
A welding head, comprising:
- a diffuser body with an inlet end and an outlet end;
- a welding tip axially located within the diffuser body and extending axially beyond the outlet end, the diffuser body having a gas outlet and a gas inlet, wherein at least one gas channel operatively connects the gas inlet and the gas outlet, and wherein the welding tip is adapted to be used for gas metal arc welding;
- and
- at least two diffusing lenses provided between the gas outlet and the outlet end of the diffuser body,
- wherein the diffusing lenses are coaxial with the welding tip which passes through a central aperture in each of the diffusing lenses, and
- wherein a first lens of the diffusing lenses has a porosity in the range of about 50 to about 150 microns, and a second lens of the diffusing lenses has a porosity in the range of about 40 to about 100 microns.
