Abstract
The present invention provides a welding system and methodology to facilitate an improved fillet weld. The system includes an arc welding subsystem providing a fillet weld that joins one or more members. The arc welding subsystem controls one or more welding parameters and utilizes one or more controlled process variables, to facilitate geometric control of a toe angle, a toe radius, a throat dimension and a penetration depth associated with the joining of the fillet weld and the one or more members. The present invention also includes optimized welding parameters, welding wire alloys, and welding gas mixtures to promote an improved fillet weld.
Claims40
A welding system, comprising:
- an arc welding subsystem that provides a fillet weld that joins one or more members;
- and
- an arc welding controller that controls one or more welding parameters and utilizes one or more controlled process variables, to facilitate geometric control of at least one of a toe angle and a toe radius, while maintaining a throat dimension and/or a penetration depth associated with the joining of the fillet weld and the one or more members.
A welding material, comprising:
- a wire alloy having a specified range of carbon of about 0.06 to about 0.15 percent, a specified range of manganese of greater than 1.40 percent to about 2.00 percent, a specified range of silicon of about 0.45 to about 0.75 percent, and sulfur specified in the range of about 0.012 to about 0.025 percent.
A method to facilitate fillet welding, comprising:
- controlling one or more weld variable parameters associated with a fillet weld;
- controlling weld member surface conditions;
- controlling wire alloy components to facilitate joining of the weld member surfaces;
- and
- controlling at least one of a toe angle and a toe radius to facilitate fillet weld performance.
A method to facilitate fillet welding, comprising:
- controlling one or more weld variable parameters associated with a fillet weld;
- controlling one or more welding gas mixture components;
- controlling wire alloy components to facilitate joining of the weld;
- and
- controlling at least one of a toe angle and a toe radius to facilitate fillet weld performance.
A welding system, comprising:
- means for providing a fillet weld that joins one or more members;
- means for controlling one or more welding parameters;
- and
- means for controlling one or more process variables to facilitate geometric control of at least one of a toe angle and a toe radius, while maintaining a throat dimension and/or a penetration depth associated with the joining of the fillet weld and the one or more members.
