Getig 4043 is a premium quality Aluminium nominal 5% Silicon alloy rod. Its lower weld deposit strength and excellent crack resistance make it suitable for GAS or GAS TUNGSTEN ARC (GTAW/ TIG) welding of cast alloys.

Suitable for Gas Welding and Gas Tungsten Arc (GTAW/ TIG) Welding applications of cast mainly(4XX & 6XX series) alloys and wrought (selected 1XXX, 5XXX & 6XXX series) aluminum alloys, except where an accurate colour match is required after anodizing.
Ultimate Tensile Strength : 110 Mpa (approx)
Thoroughly clean all areas to be joined. For the butt welding of thick plates, bevel to 650 –750 included angle. Use a Zirconiated tungsten electrode, ground to a tapered blunt point .Use high frequency stabilized alternating current (AC-HF) and Welding Grade Argon. Preheat high sections before welding, heat a spot on the base metal until it shows signs of melting and progressively add the filler rod to the weld pool.
