Embodiment 1

[0027] Step 1: Debug the welding machine before welding, and set the speed of the welding machine;

[0028] Step 2: The main material of the cylinder body is T52 steel base plate, which ensures the strength and toughness of the can. The thickness of the steel base plate is 0.2mm, and the inner and outer sides of the steel plate are respectively cut into "U"-shaped grooves by thermal cutting;

[0029] Step 3: Place a "meter"-shaped support frame inside the base material of the cylinder, and then clamp the iron sheet and the support frame with a clamp to keep the gap between the cylinder and the base material at 0.1mm;

[0030] Step 4: Use the welding method of argon arc welding double guns to make a primer inside the cylinder. The model of the argon arc welding machine is ZXT-400STG, with DC positive connection, the welding current is 130A, the voltage is 12U, and the argon gas flow rate is 8L / min. Then use manual arc welding to fill the inner weld bead of the cylinder with two...

Abstract

The invention provides an iron sheet welding technology. The iron sheet welding technology specially comprises the steps that a welding machine is adjusted, parent metal is selected, chamfering is conducted, a supporting frame shaped like the Chinese character 'mi' is placed in a cylinder, welding is conducted, and the supporting frame shaped like the Chinese character 'mi' is taken out of the cylinder. According to the iron sheet welding technology, machining efficiency is high; noise is low, and dust is avoided; the groove machining dimension is accurate; the groove is machined to be in a U shape, welding quality is high, and welding materials are saved; the supporting frame shaped like the Chinese character 'mi' is welded in the cylinder, and thus the phenomenon that circular run-out of the cylinder is high due to the fact that the diameter of the cylinder is large is avoided; deformation caused by welding is effectively controlled through the welding sequence of the technology; compared with the prior art, the welding technology has the advantages that welding deformation can be effectively controlled, and the phenomenon that an iron sheet is concave inwards after welding is avoided.

Description

technical field [0001] The invention relates to a welding process, in particular to an iron sheet welding process. Background technique [0002] Tinplate is a traditional canning material, and it is still the main canning material for food canning. Tinplate is tin-plated thin steel plate, referred to as tinplate. Tinplate has a bright appearance, good corrosion resistance and canning process performance, easy to weld, suitable for coating and iron printing. In addition to being widely used in the canning industry, tinplate is also used to make tin boxes for candy, biscuits, tea, milk powder, etc.; it can also be used for cans and boxes of certain industrial products such as chemical products and cosmetics. [0003] Before tinning, tinplate is a steel substrate with low carbon content. After welding the steel substrate, it is electroplated and resolubilized, and finally coated on the surface of the tinplate after resolvation treatment. Just one layer of oil film. [0004] ...
