In resistance welding equipment, seam welding is widely used in the manufacturing of joints with specified sealing properties, and sometimes it is also used to weld general non sealing sheet metal parts. The thickness of the welded metal material is usually between 0.1 and 2.5mm.

縫焊機就是指焊件裝配成搭接或對接接頭并放置于兩滾輪電極中間，滾輪電極加壓焊件并旋轉，連續或斷續脈沖送電，形成一條連續焊縫的電阻焊機器。可以說，縫焊機是點焊中的一種演變。

A seam welding machine refers to a resistance welding machine that assembles welded components into overlapping or butt joints and places them between two roller electrodes. The roller electrodes pressurize the welded components and rotate them, continuously or intermittently pulse to form a continuous weld seam. It can be said that seam welding machines are an evolution in spot welding.

電阻焊設備中縫焊的應用

Application of seam welding in resistance welding equipment

縫焊機主控制器選用運動控制器可編程控制器為基礎控制模塊，依據用戶要求，讓整個設備具有極強的智能性和柔性，應屬性價比和可靠性的控制器。

The main controller of the seam welding machine adopts a motion controller programmable controller as the basic control module. According to user requirements, the entire equipment has strong intelligence and flexibility, and should be a cost-effective and reliable controller.

電阻焊設備的的電極材料、電極形狀和外形尺寸，從而使電極良好的冷卻，圓錐臺形電極頭端面被視為是非常好的。端面直徑要求是為6～8mm，超出8mm就應該及時開展修磨，且焊接時焊鉗上、下電極與板件要盡量保證垂直。

The electrode material, electrode shape, and overall dimensions of resistance welding equipment ensure good cooling of the electrode, and the cone shaped electrode head end face is considered very good. The requirement for the end face diameter is 6-8mm. If it exceeds 8mm, timely grinding should be carried out, and during welding, the upper and lower electrodes of the welding clamp should be kept perpendicular to the plate as much as possible.

電極的外形尺寸擴大時，由于接觸面積擴大，電流密度減少，散熱效果提高，均使焊接區加熱程度減弱，因此熔核外形尺寸減少，使焊點承載能力減少。

When the external size of the electrode is expanded, due to the expansion of the contact area, the current density decreases, and the heat dissipation effect improves, the heating degree of the welding area is weakened, resulting in a decrease in the external size of the molten core and a decrease in the load-bearing capacity of the welding point.

中頻逆變式點凸焊機是目彰的焊接設備其一，用途廣泛，焊接變壓器體積小而輸出能量大。因其焊接變壓器頻率由現階段市電的50/60HZ提升到1000HZ,能夠很大的減少鐵芯材料重量。加上變壓器次級回路的整流二極管把電能變為直流電流提供焊機應用，能夠大在改進次級回路感應系數值，節約用戶電源能耗30%之上。

The medium frequency inverter point projection welding machine is one of the most advanced welding equipment in Muzhang, with a wide range of applications. The welding transformer has a small volume and a large output energy. Due to the increase in the frequency of its welding transformer from 50/60HZ of the current market power to 1000HZ, it can greatly reduce the weight of the iron core material. Adding the rectifier diode in the secondary circuit of the transformer converts electrical energy into direct current for welding machine applications, which can greatly improve the induction coefficient value of the secondary circuit and save more than 30% of user power consumption.
