BUTT WELDING MACHINE:
WELDCRAFT takes pleasure in introducing for the benefit of the entire wire and cable processing industry as well as metal working industry a new series of efficient machines for Butt-welding of all profile wires of Iron, Steel, Alloy and Carbon Steel, Copper, Aluminum, Brass and other light metals and their alloys.
Our machines specially designed for the Butt-welding of ferrous and non-ferrous wires in the range of 0.5 -16 mm diameters to withstand subsequent drawing. These machines are designed as portable models mounted on a movable stand with foot operation. They are constructed with particular regard for quick and easy operation; the settings for electrode spacing and upsetting pressure are calibrated directly from the different wire size to be welded. The welding process being automatic permits even unskilled workmen to operate the machine faultlessly and ensures uniform welds of high tensile strength, capable of withstanding subsequent drawing. Depending upon the material to be welded and the size of wire four different models are available. All machines are equipped with Annealing facility.
GENERAL: ?WELDCRAFT? Butt Welding Machines eliminate the outdated method of Brazing over ? lapped joints for Band-Saw Blades, Wires, Strips, etc. It avoids the solder, flux and foreign material at the joint. The process is quick and automatic giving the perfect and strong weld for the job. Butt Welding is the most modern resistance welding process which gives joint strength even 25% higher that the parent metal.
WELDING PROCESS: The ends of the Blade/Wire to be joined are cut straight exactly at right angle and free of burrs. Welding Pressure, Current & Upsetting (Initial opening gap) are set accordingly to size of the job. The blade ends are then rigidly clamped in the center of the gap. (Ends should be in touch)
WELDING CYCLE: The cycle starts by turning the Upsetting ? Way Switch clockwise and depressing the switch ?Welding? marked position by pressing switch downwards the welding cycle starts and the two end are heated up to forging temperature in few seconds and automatically forged. At this instant the welding current switches off automatically and the job is welded.
ANNEALING OPERATION: The Upsetting ? Way switch or cam is turned to ?Annealing? position marked, the welded job is again clamped in the centre of extended jaw distance, and here jaws are opened maximum. Now press the push button / annealing switch, the job is annealed, in order to normalize the brittleness in welded zone. Depending upon the type of material and the hardness the annealing process must be repeated several times, if needed.
CAUTION: NEVER PRESS BOTH WELDING SWITCH AND ANNEALING SWITCH SIMULTANEOUSLY.
SHEARING & GRINDING ATTACHMENTS: Available at EXTRA COST.
