Abstract
A method and apparatus for producing high quality welding rod including a first forming of an ingot under triple vacuum forming techniques; a continuous mechanical de-scaling at all stages, including, but not limited to, final drawing; performing ultrasonic inspection; using boron nitride covered by potassium silicate during billet extrusion; performing an unusual electrolytic purification process, and a final controlled packaging process.
Claims3
The method for producing high quality welding rods which consists of:
- the following procedures vacuum forming of ingots, shapes, billets, bars and wire hereafter jointly referred to as "shapes" a multiplicity of times;
- constant mechanical removal of oxides from the exterior surfaces of all shapes;
- cogging and hot rolling redraw bars from ingots and billets;
- performing ultrasonic inspection at each of the foregoing procedures;
- electrolytic cleaning of all shapes;
- performing vacuum annealing of the shapes;
- cutting and straightening shapes;
- hand wiping the shapes with solvent;
- attaching identification tags to the shapes;
- enclosing the shapes in vapor barrier foil envelopes;
- placing desicant in the envelopes;
- evacuating air from the envelopes and replacing the air with inert gas;
- sealing the envelopes;
- placing the envelopes in a protective outer package.
11 more elements
The method of lubricating and protecting welding rod including:
- 1 coating each individual rod with boron nitride;
- and coating each boron nitride coated rod with potassium silicate.
A welding rod comprising:
- an elongate length of welding rod material;
- a coating of boron nitride completely covering the elongate length of welding material;
- and a coating of potassium silicate completely encasing the boron nitride covering over the elongate length of welding material.
