Welding machine is dividesd into a number of string, follow me and learn more about that.
Can The Aluminum Plate Be Welded?
Can the copper plate be welded? Copper panels can be resistance welded. Due to the various copper thicknesses, there are also differences for the welding of copper panels. If depth is within 1mm, normally you can directly select IF spot welding, and welding will be beautiful. If thickness is more than 1mm, it is encouraged to utilize the brazing filler alloy, which can also achieve the effect of firm and gorgeous welding.
Additionally, the aluminum plate may also be welded with stainless steel plates and reduced carbon steel plates. The Good Welding IF inverter DC spot welder adopts a quick welding mix method, where iron and aluminum plates or stainless steel plates are condensed to a nugget with a big pressure when a sizable current across through the aluminum plate and the resistance heat melting metal hasn't dispersed.
Why do aluminum spot welds burst?
When welding along with the current flows through the aluminum surface, made warmth will permeate aluminum surface. However, due to the strain of the top electrode, the upper electrode will press down. The electrode is pressed into the pit, so that the aluminum inside this pit will splash out to form a frying joint.
In this case, it is encouraged that the Friction Stir Welding process should be used to weld the aluminum metal. All aluminum products involved in the connection can be linked by Friction Stir Welding process. By using Friction Stir Welding to aluminum metal welding seams, in the instance of non-grooving with no filling the wire, use solid-phase connection to directly plasticize the foundation material after the parent substance under the mixing head forging and achieves re-recrystallization. The dimensions of weld crystal grain is smaller than the parent metal by an order of magnitude, and the possessions of the weld are near that of the parent alloy. The aluminum alloy is perfectly connected.
The technical characteristics of Friction Stir Welding are:
1. Direct welding for base metal, no demand of groove opening and wire filling;
2. It's unnecessary to remove the substance oxide coating before welding. No vacuum and shielding gas are needed during welding. No component burned after welding.
3. The weld grain structure is forged. The crystal structure is isotropic. The properties are near the parent substance.
Nut conveyor
The welding nut is usually transported to the welding place by nut conveyor, so the nut is simply buckled onto the nut electrode, using the IF DC spot welder achieves instantaneous discharge. There are generally two types of nuts which are welded, hexagon nuts and four-corner nuts. Hex nuts have three protruding welding factors. Firstly, place the perforated steel plate to the nut electrode, the nut is fed by the vibration plate of this nut conveyor to the move gun and is quickly implanted onto the nut electrode; enter the conclusion signal for spot welder and the spot welding machine begins welding. The usage of a nut conveyor may eliminate potential security hazards of this welder's hand and also greatly increase production efficiency. Guangzhou GOODWELD Electromechanical Equipment Co., Ltd. has also developed a precision nut welding device with a misplaced, leak-proof, and also anti-backup welding nut, so the precision of the welding nut can be around 100%.
Method and use of galvanized sheet spot and projection welding equipment
The method and use of welding using galvanized sheet: When the galvanized sheet adopts resistance welding procedure, spot welding or projection welding are all acceptable.
Spot welding procedure: if spot welding is in the upper and lower welding mind, the melting nugget region is large, the weld depth is broad, and the welding is relatively firm. The disadvantage is that the chemical components of galvanized sheet are too lively; if the melting point is up to 495 degrees Celsius, zinc vapor begins to emerge. From the welding pressurization process, zinc vapor may easily adhere to the welding head. When the zinc layer of the welding head is thick enough, it blocks the current output and reduces welding ability, and it requires frequent grinding of electrodes.
To solve this problem, now most folks adopts the projection welding procedure. The projection welding process should punch out a number of convex starting points on a panel beforehand, and use scientific approach to calculate the width of the convex point, the diameter of the form of the convex stage, the shape and the height are based upon the material thickness. (The calculation of the diameter, shape and height of the bump is going to be clarified in a later article). The size of these bumps determines the nugget and penetration of the weld. The amount of bumps should like be determined based on the size of the material. The projection welding process is utilized for galvanized sheet welding. Comparing to spot welding, projection welding procedure has the following benefits: 1 ). The speed of welding is fast; 2. Welding is company. 3. The amount of sticky zinc level in welding head is greatly reduced. 4. 5. The item appears neat and lovely. 6. The production efficiency increases by several occasions. 7. Less vaporization of zinc vapor, no pollution.
Advantages of stainless steel spot welding equipment
1, Welding conditions
The response rate of stainless steel spot welding equipment is 1ms. The current can reach the set value quicker, and get more accurate analysis of parameters; balanced three-phase input, steady parameter; continuous current effect Is Quite stable;
2, welding caliber
Due to the elevated frequency of 1000Hz for its stainless steel spot welder, a solid secondary current output capability, a flat wave contour, and a wide assortment of stable atomic dimensions, virtually no splashing occurs, and the current in the main welding stage raises obviously, and the surface quality of the solder joint is good.
3, Adaptability
Applicable to a variety of welding materials, including aluminum alloy, aluminum and other substances with rapid thermal conductivity and poor welding. For the welding of galvanized sheet along with regular multilayer sheet, the welding quality is much higher than that of the energy frequency welding machine;
4, Transformer
Transformer is small in size and reduced in input electricity;
5, Energy utilization
Balanced three-phase load, power factor is up to 0.9 or more, energy conserving (according to the record of General Motors Corporation of the United States, mid-frequency place welding saves 4 cents per welding combined comparing to power frequency location welding);
Guangzhou GOODWELD Electromechanical Equipment Co., Ltd. adopts technology from German, imported components and innovative manufacturing process with 20 years. The spot welding equipment series can offer all aspects of brazing and aluminum welding technologies.
