WELDING

“ Welding is a joiningprocess that

producescoalescence of

materials byheating them to

weldingtemperature, with

or without theapplication of

pressure or by theapplication of

pressure alone, and with or without

the use of fillermaterial ”

The Würth welding range representscutting edge technology and guaranteesthe latest state-of-the-art applicationswhile at the same time being underconstant advanced development. Thus,Würth continues to lead the way insupporting welding education andtechnology development.

can be carried out quickly and safely• High resistance to running• High abrasion resistance• Optimal for spot welding

Zinc Spray Perfect contains zinc, and therefore offeroptimum, active cathodic protection against corrosion. If thesurface is damaged, the zinc coating sacrifices itself(sacrificial anode) and therefore protects the metal againstrust. The remaining products offer protection of the entiresurface treated against rust. If the surface is damaged, themetal is not protected further.

Use the gun to spot-weld the weld pins to the surface of dents.For elongated dents the pins should be welded approximatelyevery 3cm depending on dent shape. The dent puller is thenpushed onto the spot weld pins and tightened by means ofthe knurled tensioning nut. Now operate the sliding weight topull and straighten out the dent quickly and simply. The pullerpins are available in 2.0 and 2.6mm diameter and arewelded and pulled with the same chuck. Finally, snap off thepins at the head and grind down.

Plasma weldingWith plasma welding the electric arc burns between a non-melting electrode and the workpiece. With a nozzleand with compressed air fed in it is additionally constricted, which considerably increases the intensity and stability.This constriction results in a highly heated gas in the torch with a high energy content, the electrical energy of whichis directly converted to heat. This ionised gas, which the arc transfers to the workpiece, is referred to as the plasma. With the plasma cutting method, steel, stainless steel, aluminium, copper, cast iron, brass etc. are materials thatcan be cut. The special advantages are: Due to the high energy density of the plasma arc, a high cutting speed is achieved.The cuts are steep, flash and distortion-free and highly economical. The easy handling and the use of simplecompressed air as cutting gas offers unlimited possibilities. These include steel construction, metal construction, installation, container construction etc. 21

Electrode hand weldingThe electric arc burns betweenthe workpiece and a meltingelectrode. This means theelectrode simultaneouslysupplies the additive. The rodelectrode is clamped in anelectrode holder and guided bythe welder along the seam. Rodelectrodes are generallycoated. The coating also meltsbefore the outside air enters.After the molten pool cools, slagis removed.

Devices with (S) symbol can also be used under increased electrical danger.Inverter welding units have especially good welding properties, and aretherefore also well suited for special electrodes. Nearly all weldablematerials can be welded with rod electrodes, e. g. construction steel, boilersteel, pipe steel, cast steel, stainless steel, hardfacing steel etc.Electrode hand welding is easy and safe. The compact units are simple to useand easy to transport. As no gas is required, it is also possible to weldoutdoors, even on windy days. Electrode welding units are used in all areas,from industry to skilled trades.

MIG-MAG weldingWith the MIG-MAG process(MIG = Metal Inert Gas/MAG =Metal Active Gas), the electricarc burns between the melting,automatically fed welding wire(= electrode) and the workpiece.A separately added gas protectsagainst the arc and the weldingzone against the entrance ofoutside air. The shielding gasand the welding wire must beadapted to the basic material.

The weldable materials are: Aluminium, aluminium alloys.Process: MIGThe wire electrode must be adapted to the material to be welded accordinglyShielding gas: Ar, He or mixturesGeneral construction, boiler and pipe steelProcess: MAGWire electrode: SG 1-3Shielding gas: Mixed gas (Ar/CO2) or CO2High-alloyed steelsProcess: MAGWire electrode: In accordance with the material to be weldedShielding gas: Mixed gases (e.g. Ar/CO2 or Ar/CO2/O2)

Due to the enormous advantages, MIG-MAG welding is one of the mostfrequently used welding methods today. The high welding speed, the minimalreworking required and the low distortion ensure high economy. The highweld strength, the outstanding thin-sheet properties and the simple, safe usewith steel, aluminium and stainless steel make the process universal.

MIG braze weldingStandard-compliant: MSG(Metal Shielding Gas) solderingis a brazing method. The electricarc burns between the melting,continuously fed solder wireelectrode and the workpiece.The added shielding gasprotects the arc and the liquidsolder against the influences ofthe ambient air. It is as easy touse as MIG/MAG welding.For joining galvanised metal

sheets, MIG braze-welding offers clear advantages compared toMIG/MAG welding.Due to the low melting temperature of the solder wire (approximately.1000°C), only minimal burning of the zinc content occurs in the area of thedirect soldering zone (zinc melts at 419°C, vapourises at 906°). The solderwire has a higher corrosion resistance and enables easier surface machining.The solder wires consist of a copper-based alloy with alloy shares, e. g. siliconor aluminium.Due to the low addition of heat, little distortion occurs even with very thinmetal sheets. Coated (galvanised, phosphated, aluminised) and uncoatedsteel sheets, stainless steel and steel/stainless steel compounds (black-and-white compounds) can be soldered. Soldered seams have excellentconnection strength.Shielding gas: Pure argon or argon with small amounts of additives.Galvanised thin sheet is used today in automobile construction, in thebuilding industry, air conditioning technology, in household appliances andthe furniture industry. MIG brazewelding is ideal for these uses.

TIG weldingWith the TIG method (TIG =Tungsten Inert Gas), the electricarc burns between the non-melting tungsten electrode andthe workpiece. The arc is veryintense and can be guidedextremely well.A separately fed argonshielding gas protects the arcand the welding zone from the entry of the atmosphere. If necessary, additional material

is added by hand or with a special cold wire feed.Steel, stainless steel, copper, titanium etc. are welded with direct current. Theelectrode is connected to the negative pole and ground to a point.Aluminium, magnesium and their alloys are welded exclusively withalternating current to tear open the oxide skin. The electrode is blunt. Duringwelding a round to balled shape results. With modern inverter currentsources, it is also possible to weld with a pointed tungsten electrode.The advantages of the TIG welding method: The simple use and control ofthe arc enable a very convenient, clean working process. The low scaleformation on the workpiece, the narrow welding zone, the elimination of theneed for flux and the splash-free arc provide for clean, exact seams withoutslag inclusions and without major reworking.
