TH55844B - Hard wire without quenching for welding - Google Patents

Abstract

DC60 (02/12/52) Wire without plating for welding. Of this invention contains C 0.4 to 0.12 mass%, Si: 0.5 to 1.1 mass%, Mn: 1.0 to 1.7 mass% Ti, not greater than 0.03 mass%, and the rest is Fe. Additionally, the equation: Si + Mn + (10xTi ) Less than or equal to 2.5 is fulfilled, where Si, Mn and Ti represent the available quantities of each element. Element in wire The toughness of the wire is 900 to 1300 (N / mm2). Potassium compounds. It is present in amounts of 2 to 10 ppm in terms of potassium MoS2 0.01 to 0.5 g per 10 kg of wire and oil containing 0.3 to 1.5 g of polyisobutene per 10 kg of strands. The wire on the surface and / or abruptly under the surface of the non-plated wire containing such components, it is possible to adjust Improved both the feedability and arc starting characteristics of the impregnated wires for welding. Of this invention there are C: 0.4 to 0.12 mass%, Si: 0.5 to 1.1 mass%, Mn: 1.0 to 1.7 mass% Ti not greater than 0.03, mass% and the remainder Fe. Additionally, the equation: Si + Mn + ( 10xTi), less than or equal to 2.5, is metered, where Si, Mn, and Ti represent the available quantities of each element. Element in wire The toughness of the wire is 900 to 1300 (N / mm2). Potassium compounds. It is present in amounts of 2 to 10 ppm in terms of potassium MoS2 0.01 to 0.5 g per 10 kg of wire and oil, which contains 0.3 to 1.5 g of polyisobutylene per 10 kg of Immediate and / or instantaneous wires under the surface of the unpainted wires containing such components, it is possible to adjust Cooked both the feedability and the arc start feature of the wire:

Claims (3)

1.1.0 to 1.7 mass% Ti in a restricted quantity of not more than 0.03 mass% and the remainder Fe. In addition, the available quantities of Si, Mn, and Ti, which are limited in order to satisfy That is defined by equation (1): Si + Mn + (10xTi) is less than or equal to 2.5 (1), where Si, Mn, and Ti represent the available quantities of each element. Element in the wire where the toughness of the wire is 900 to 1300 (N / mm2) and where the potassium, MoS2 and at least water One type of it is selected from a group consisting of mineral oil, animal oil, vegetable oil and synthetic oil, it is present on the surface and / or immediately under the surface of the skin. The uncoated wire and the amount of potassium compound that it contains is 2 to 10 ppm in the potassium term, the amount of MoS2 to be contained is 0.01 to 0.5 g per 10 kg of wire. And the amount of oil that would be 0.3 to 1.5 g per 10 kg of wire. 2. Solid wire without plating for any required welding Corresponds to claim 1 where MoS2 particle diameter is 0.1 to 10 (mu) m. 3. Solid wire without plating for custom welding This is consistent with claim 1, where potassium compounds are potassium borate.
