焊接专机形式多样,所以应根据不同工件的形状大小,材质,厚度及焊接成形要求不同的焊接电源。根据日常实践总结出以下几点关于山东焊接专机的焊接热源:
There are various forms of special welding machines, so different welding power sources should be required according to the shape, size, material, thickness and welding shape of different workpieces. According to daily practice, the following points are summarized about the welding heat source of Shandong welding machine:
1.等离子弧焊
1. Plasma arc welding
等离子弧焊是一种不熔化ji气体保护电弧焊,它是利用电ji和工件之间的压缩电弧实行焊接的,所用电ji通常是钨ji。产生等离子弧的等离子气可用氩气,氮气、氦气或其中两者的混合气。同时还通过喷嘴用惰尾气体保护,焊接时可以选择是否填充金属.
Plasma arc welding is a kind of gas shielded arc welding without melting. It uses the compressed arc between the electric ji and the workpiece to weld. The electric ji used is usually tungsten ji. The plasma gas that generates the plasma arc can be argon, nitrogen, helium or a mixture of the two. At the same time, the nozzle is also protected by inert gas, and whether to fill metal can be selected during welding
等离子弧焊接时,由于其电弧挺直,能量密度大,因而电弧穿透能力强。等离子焊接可产生小孔效应,因此对于一定范围内厚度的大多数金属可以进行不开坡口焊接,并能保证熔透和焊缝均匀一致。因此,等离子焊接的生产效率高,焊缝质量好,但等离子弧焊设备比较复杂,对焊接工艺及参数控制要求较高(我司在这方面有自己的核心特长),对于1mm以下的ji薄板焊接,用微束等离子较易进行焊接。
During plasma arc welding, due to its straight arc and high energy density, the arc penetration ability is strong. Plasma welding can produce small hole effect, so most metals with a certain thickness can be welded without groove, and can ensure the penetration and weld uniformity. Therefore, the production efficiency of plasma welding is high and the weld quality is good, but the plasma arc welding equipment is relatively complex, and the requirements for welding process and parameter control are high (our company has its own core expertise in this regard). For the welding of ji thin plates below 1mm, it is easier to weld with micro-plasma.
2.埋弧焊
2. Submerged arc welding
埋弧焊是以连续送丝的焊丝作为电ji和填充金属。在焊接专机焊接时在区上覆盖上一层颗粒状焊剂,电弧在焊剂层下燃烧,将焊丝端部和局部母材熔化,形成焊缝。在电弧热的作用下,一部分熔剂熔化成熔渣并与液态金属发生冶金反应,熔渣浮在金属熔池的表面,一方面可以保护焊缝金属,防止空气的污染,另一方面可以使焊缝金属缓慢冷却.
Submerged arc welding uses the welding wire with continuous wire feed as the electric ji and filler metal. When the welding machine is used for welding, a layer of granular flux is covered on the area, and the arc burns under the flux layer, melting the end of the welding wire and local base metal to form a weld. Under the action of arc heat, part of the flux melts into molten slag and reacts with liquid metal metallurgically. The molten slag floats on the surface of the metal molten pool. On the one hand, it can protect the weld metal and prevent air pollution, on the other hand, it can make the weld metal slowly cool

3.钨ji气体保护电弧焊
3. Tungsten ji gas shielded arc welding
这是一种非熔化ji气体保护电弧焊,是利用钨ji和工件之间的电弧使金属熔化而形成焊缝的,焊接过程中钨ji不熔化,只起电ji的作用。同时由焊接专机焊炬的喷嘴送出氩气和氦气作为保护气体,另外可根据需要另外填充金属(我公司生产有专业的送丝机)。钨ji由于很好地控制好热输入,所以它是连续焊接薄板金属和打底焊的一种ji好方法,焊接电流采用脉冲形式,因此常常用来进行管道底层的焊接,以达到单面焊双面成形的目的,这种方法几乎可以用来所有金属的焊接,尤其适用于铝镁这些能形成难熔氧化物以及像钛锆这些活泼金属的焊接,这种焊接方法焊缝质量高,但与其它电弧焊相比,其焊接速度较慢。
This is a kind of non-molten ji gas shielded arc welding. It uses the arc between tungsten ji and the workpiece to melt the metal to form a weld. During the welding process, tungsten ji does not melt, but only acts as electric ji. At the same time, argon and helium are sent out from the nozzle of the welding torch of the special welding machine as the shielding gas, and additional metal can be filled according to the needs (our company has a professional wire feeder). Due to the good control of heat input, tungsten is a good method for continuous welding of sheet metal and backing welding. The welding current is in the form of pulse, so it is often used to weld the bottom layer of the pipe to achieve the purpose of single-sided welding and double-sided forming. This method can be used for the welding of almost all metals, especially for the welding of aluminum and magnesium which can form refractory oxides and active metals such as titanium and zirconium, This welding method has high weld quality, but its welding speed is slow compared with other electric arc welding methods.
4.熔化ji气体保护焊
4. Fused ji gas shielded welding
这种焊接方法是利用连续送进的焊丝与工件之间燃烧的电弧作热源,由焊炬喷嘴喷出的气体来保护电弧进行焊接的.
This welding method uses the burning arc between the continuously fed welding wire and the workpiece as the heat source, and the gas from the welding torch nozzle protects the arc for welding
熔化ji气体通常用的气体有氩气,氦气,co2,氧气或这些气体的混合气。以氩气和氦气作为保护气体时简称为MIG焊,活性气体(co2、氧)或活性气体与惰性气混合气作保护气时简称为MAG焊
The gases commonly used to melt ji gas include argon, helium, carbon dioxide, oxygen or a mixture of these gases. MIG welding is referred to as MIG welding when argon and helium are used as shielding gas, and MAG welding is referred to as MAG welding when active gas (carbon dioxide, oxygen) or active gas and inert gas mixture are used as shielding gas
熔化ji气体保护焊的主要优点是可以方面地进行种位置的焊接,同时具有焊接速度较快,熔敷率较高等优点。
The main advantage of fusion ji gas shielded welding is that it can weld different positions in an all-round way, and has the advantages of faster welding speed and higher deposition rate.
5.药芯丝电弧焊
5. Flux-cored wire arc welding
药芯丝电弧焊是利用连续送进的焊丝与工件之间燃烧的电弧作热源来进行焊接,可以认为是熔化ji气体保护焊的一种,所以使用的焊丝是药芯焊丝,焊丝的芯部有不同组成部份的药粉,焊接时外加保护气体,药粉受热分解或熔化,起着造气、造渣保护熔池,渗合金及稳弧作用.
Flux-cored wire arc welding uses the burning arc between the continuously fed welding wire and the workpiece as the heat source for welding. It can be considered as a kind of melting ji gas shielded welding. Therefore, the welding wire used is flux-cored welding wire. The core of the welding wire has different components of powder. When welding, the protective gas is added. The powder is decomposed or melted by heat, which plays the role of gas making, slag making, protecting the molten pool, alloying and stabilizing the arc
6.电阻焊
6. Resistance welding
是以电阻热为能源的一种焊接方法,包括以熔渣电阻热为能源的电渣焊和以固体电阻热为能源的电阻焊,以固体电阻热为能源的电阻焊,主要定位焊,缝焊、凸焊及对焊等。
It is a welding method using resistance heat as energy source, including electroslag welding using slag resistance heat as energy source, resistance welding using solid resistance heat as energy source, resistance welding using solid resistance heat as energy source, mainly positioning welding, seam welding, projection welding and butt welding.
电阻焊一般是使工件处于一定电ji压力的作用下并利用电流通过工件时所产生的电阻热将两工件之间的接触表面熔化而实现连接的一种方法。通常使用较大电流,为了防止在接触面上发生电弧并为了锻压焊缝金属,焊接过程中始终要施加压力。
Resistance welding is generally a method to make the workpiece under the action of a certain electrical pressure and use the resistance heat generated when the current passes through the workpiece to melt the contact surface between the two workpieces to realize the connection. Generally, large current is used. In order to prevent electric arc on the contact surface and forge the weld metal, pressure should always be applied during welding.
此外还有高能速焊、电子束焊,激光焊,激光电弧复合焊,钎焊、高频焊、气焊、爆炸焊、摩擦焊,超声波焊,扩散焊等。
In addition, there are high-energy speed welding, electron beam welding, laser welding, laser arc composite welding, brazing, high-frequency welding, gas welding, explosive welding, friction welding, ultrasonic welding, diffusion welding, etc.
