Easily overlooked problems in steel structure welding processing to prevent casting errors

2022-02

The main material of steel structure is steel, and it is also one of the most important types of building structures at present. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates. Each part or component is connected by welding, bolts or rivets. Steel structure weight than other building materials light, simple construction, widely used in some large factories, sports venues, high-rise buildings and other buildings. Welding is a very important part of the whole steel structure building. Therefore, once there is any negligence in this process, it is possible to make major mistakes.

Copper electrode custom factory introduction, copper electrode is also known as purple copper electrode. The pure copper wire is used as the core, and the surface is coated with the electrode composed of low hydrogen type drug skin. Copper electrode welding process: 1. Copper electrode customization factory said that welding preheating and copper electrode drying can be preheated to 300-350 degrees before welding, and the electrode can be baked at 150-200 degrees for 1 hour. 2. The straight-line transportation method can be used for copper electrode welding. The sooner the better. In order to reduce metal oxidation, the diameter of the electrode and the welding current are increased within the allowable range of the weldment. When welding V-shaped or X-shaped grooves, defects such as incomplete penetration may occur at the root during welding. The main reason is that the electrode is too thick, the groove angle is small, the arc is too far from the root, the heat conduction of copper is fast, and the arc heat is insufficient. Therefore, in order to ensure the root penetration force, should be appropriate to increase the groove angle or increase the gap. Multi-layer welding V-groove, a layer to use a diameter of 3-4mm electrode. After that, the diameter of the electrode can be increased layer by layer and oscillated laterally. When welding, the arc should be directed towards the molten pool so as not to blow on the side of the groove metal. The electrode is fed at a constant speed along the center of the weld and moves in the welding direction to prevent liquid metal and slag from flowing out of the molten pool to form weld flare. Replace the electrode action should be fast, when welding high temperature

According to the characteristics of the electrode skin, the electrode can be divided into two categories: acid electrode and alkaline electrode. Electrode drug skin contains a large number of acidic oxides (TiO2, SiO2, etc.) called acidic electrode. Acid electrode AC and DC dual-purpose, welding process performance is good, arc and spatter small, slag flow is good, slag removal is easy, the weld appearance is beautiful, because the coating contains more silicate, iron oxide and titanium oxide, etc., has a strong oxidation performance, but the mechanical properties of the weld, especially the impact toughness is poor. It is suitable for general low carbon steel and low alloy structural steel with low welding strength, and is most widely used. Welding rod. The skin containing a large amount of alkaline oxides (CaO, Na2O, etc.) is called alkaline electrode. The electrode mainly relies on the decomposition of carbonate (such as CaCO3 in marble) to decompose CO2 as a protective gas. In the arc column atmosphere, H acts as a protective gas. The H partial pressure in the arc column atmosphere is low, and CAF2 and H at high temperature of fluorite combine to generate hydrogen fluoride HF, thus reducing the hydrogen content in the weld, so the alkaline electrode is also called low hydrogen electrode. The welding rod is used for welding, and its role in the welding process is as follows: 1. Improve the stability of arc combustion. The light welding rod without coating is not easy to ignite arc, even if it burns
