焊接鋼筋鋼絲網(wǎng)的常見方式：
Common ways of welding steel wire mesh:
1.電渣工作壓力焊接：在左右焊接鋼筋中間放一小片導(dǎo)電性劑（軸承鋼球，不銹鋼焊條等），安裝劑盒并添充助焊劑，并應(yīng)用交流電焊機(jī)聯(lián)接起動(dòng)電弧點(diǎn)燃的電源電路。再渣池產(chǎn)生后，鋼筋熔融而且電弧平穩(wěn)了一定時(shí)間。在關(guān)閉電源另外，應(yīng)用手動(dòng)式卡緊組織卡緊頂部以參雜物和汽泡，進(jìn)而產(chǎn)生連接頭。這類焊接關(guān)鍵用以延長(zhǎng)現(xiàn)澆板鋼筋鋼筋混凝土預(yù)制構(gòu)件中的豎直鋼筋。
1. Electroslag working pressure welding: put a small piece of conductive flux (bearing steel ball, stainless steel electrode, etc.) between left and right welding reinforcement, install flux box and add flux, and connect the power circuit ignited by starting arc with AC welding machine. After the slag pool is produced, the steel bar is melted and the arc is stable for a certain time. In addition, manual clamping structure is used to clamp the top to remove the impurities and bubbles, and then the connector is generated. This kind of welding key is used to extend the vertical steel bars in the reinforced concrete precast members of cast-in-place slabs.
2.電阻點(diǎn)焊：螺母點(diǎn)焊機(jī)的左右電極與交叉式鋼筋觸碰并接入電流量，交叉式鋼筋的點(diǎn)接觸的電阻器很高。電流量造成的發(fā)熱量將使鋼筋熔融，另外，電極將對(duì)鋼筋加壓并焊接。它用以焊接鋼筋網(wǎng)，鋼筋框架和別的鋼筋的交叉式聯(lián)接。
2. Resistance spot welding: the left and right electrodes of the nut spot welding machine touch the cross type steel bar and connect the current amount. The point contact resistor of the cross type steel bar is very high. The heat generated by the current will melt the steel bar, and in addition, the electrode will pressurize and weld the reinforcement. It is used for welding steel mesh, steel frame and other steel bar cross connection.
3.鋼筋標(biāo)準(zhǔn)氣壓焊：鋼筋的尾端被一定占比的co2（純凈度≥98.5％，罐裝壓力低于510kg/cm2）加溫到塑性變形情況（溫度約13201340攝氏），并另外加壓加溫，然后釋放超出3000kg/cm2的工作壓力將鋼筋焊接在一起。
3. Standard gas pressure welding of steel bar: the tail end of steel bar is heated to plastic deformation (temperature is about 1320-1340 ℃) with a certain proportion of CO2 (purity ≥ 98.5%, canned pressure is lower than 5-10kg / cm2), and then the steel bars are welded together by releasing the working pressure exceeding 3000kg / cm2.
4.閃光對(duì)焊：對(duì)焊機(jī)用以使鋼筋的2個(gè)一部分觸碰。在低壓和強(qiáng)電流量功效下，將鋼筋加溫到一定溫度并變軟，隨后徑向加壓頂部以產(chǎn)生對(duì)焊頭，該對(duì)焊頭徑向拓寬。
4. Flash butt welding: butt welding machine is used to make two parts of steel bar touch. Under the effect of low voltage and high current flow, the steel bar is heated to a certain temperature and softened, and then the top is pressurized radially to produce butt welding head, which is radially widened.
5，電弧焊：運(yùn)用電弧二保焊機(jī)在電極與焊接件中間造成高溫電弧，使在電弧點(diǎn)燃范疇內(nèi)的焊絲與焊接件溶化，凝結(jié)后產(chǎn)生連接頭或焊接。
5. Electric arc welding: high temperature arc is generated between the electrode and the weldment by using the secondary arc welding machine, which dissolves the welding wire and the weldment within the arc ignition scope, and generates the joint or welding after condensation.
