AUTOMATION OF THE THIN-SHEET ZINC COATED STEEL AND NON- FERROUS METALS WELDING AND SOLDERING PROCESSES

A modern welding production is characterized by the use of fundamentally new
processes and technologies, that by virtue of the features require complex
mechanization and automation.
Automation is the tendency of technical progressto replacemental and physical
work of a manwith the work of machines and mechanisms.
Automation helps to ensure the specified quality of welded joints within the
whole party of the same products, to increase productivity and save working time,
saving labor, energy and material resources. In addition it can reduce the cost of
manufacturing of any welded product.
We conducted research work on automation of the thin-sheet zinc coated steel
and non-ferrous metals welding process.
It resulted in constructing and assembling of automatic MIG – MAG welding
and MIG-soldering complex machine. This unit consists of a frame with a guide-rail.
The mechanism moves on a frame, while welding torch AL2300/AW2500 produced
by Fronius is fixed automatically with the special clamping device. The mechanism
of moving provides the set speed of welding and pulling force.
The unit is equipped with a DC motor, the use of which allows to adjust the
welding speedsmoothly. The welding speed is set according to the calibration curve
with the help of controller. Controller is located on the remote control.
The construction of setting gives an opportunity to carry out theprocess
ofwelding of the butt and fillet welds.
Welding machine can be equipped not only with the welding torch, but other
types of torches. For this purpose, they must be similar to the latter one in the size
and weight.
There are plans to test the installation for pulsed arc welding of thin-sheet
structures of high-alloy steels and non-ferrous metals in the mixture of shielding
gases and soldering of zinc coated steel joints.
It would be very perspective to connect the installation to the personal computer.
It would give an opportunity to manage this welding process with the help of a
computer.
