Nut weldingNut weldingOn the basis of our experience and close collaboration with our customers from the automotive sector, we havedeveloped a standardized welding electrode method for nuts and screws in the M4–M12 range. Pins and isolatingbushings are made of KCF material or ceramics. Standardization has reduced costs and enabled the whole range ofproducts to be available from our stock.For your convenience, all products are available with a wide variety of mounting systems, so that you do not need tore-arm your welder (see pages 18–21).Ceramic pinsAllows of the optimization of the projection weldingprocess. The adaptation of insulated pins has revolutionizedprojection welding. Standardized pins made ofstainless steel with thermo-setting resin insulation havenow almost been replaced by pins made of ceramicsand KCF*. Insulators guarantee process stability, whichmakes your production cheaper.CERAMIC PINS:KCF* PINS:––Ideal insulator,––20–30 µm deep insulating layer,––Maintenance-free up to 1400° C,––Insulation stability at high temperatures,––No whiskers or shunting effect,––No whiskers or shunting effect,––High hardness and impact strength,––Hardness of 50 HRC,––Perfect positioning,––Perfect positioning,––Cost-reduction by means of longer life,––Low operational cost,––Better productivity,––No isolation bushing in electrode design,––Standardized product group.––Standardized product group.*KCF alloy – Ferritic stainless steel with additional chrome and aluminium. This alloy forms an oxide film on the surface when carrying out special coating using hightemperature. The principal component of this coating is chemically stable aluminium. Properties: chemical stability, heat-resistance, high hardness and insulationcoating of 20–30 µm.16 www.laska.com.pl

Ceramic pinsNon-standard pinsFor individual use, we produce ceramic pins andbushing according to customer specification.If you lack the documentation, you can put thedimensions on our default drawing and send it tous with a request for a quotation.Special steel toolingWe are able to produce special tooling for both single machines andcomplete production lines according to your specification.Materials:––––––––Quality steel,Powder steel,Non-ferrous metals and alloys,Thermo-setting resins.www.laska.com.pl17
