The use of oxyacetylene Welding Electrode. Operation process is as follows:
(1) clean-up piece, non-ventilated place, slow cooling, can not quench, conditions can be covered with asbestos felt.
(6) the workpiece is cooled to room temperature, if necessary, to the welding surface grinding to the required size and shape.
(7) cleaning the workpiece to remove all splash, slag and so on. Surfacing, the use of a neutral flame (flame carbide can slant) tip in a smooth uniform surface
on the move, the flame front alloy welding heat (careful not to touch the tip of Yan Xin alloy particles), the Stainless Steel Electrode in the molten matrix alloy , along with
carbide particles are also falling. Solidification of molten metal in the matrix before
Welding operation properly, the weld overlay is a sign of satisfactory quality: after cooling, shiny surface of cladding layer golden cladding layer and the substrate
metal matrix alloy with good alloy particles tightly packed and uniform, prison to be welders exposed metal surface gloss.
(2) take the flat welding position welding, for which the tire can be used with the appropriate thickness for the control of welding can be used to limit thick
blocks.
(3) with a neutral flame preheating, Yanxin Do not touch the surface, the distance to 25mm is appropriate.
(4) weld surfacing alloy layer. Make particles with yd type electrode arrangements, the alloy electrode can be used left hand pull to get, or another person
holding a primer for the pull rod or stick of graphite rods in a particle near the fiddle quickly, so neatly arranged in uniform. Cladding layer thickness according to
design requirements control.
(5) parts after welding, the welding on the solid metal embedded in the matrix in
