Welders are needed in many industries, and without them there may not be so many fine fashionable metal products. Our own home needs a small welder. Welding is a small mechanism that is shared by the authors, so that they do not waste money to buy it。
I. Small welding mechanisms
Method i: welding by 102 mm x 6 mm copper line (commonly known as copper rows) by 102 mm, by welding to two-half, by the primary circle (insulation layer with secondary lines) and by the other half by the other pillar. The layer of the copper line shall be separated by an insulation film to allow for the dissipation of the heat and, if necessary, may be connected to the fan specifications (voltage, direct flow, etc.)。
Method ii: select to use a cross-section of approximately 40cm2 of the silica steel cores around two columns of each of the vernacular steel cores, with a primary coil of 2 mm with a twilight copper line, with a primary coil of 330 mm (220 v for electrical exchange), with a secondary 2 mm x 6 mm of copper line (commonly known as copper platoon) with an insulation layer of 40 siphons, with a sub-column of 2 mm x 6 mm insulation, with a "weak" of 35 sills, with an empty voltage of 50 v, with an air pressure of 60 v, with an empty voltage of 15 wilders, and a further 15 wrinkle of 15 siphons, with an air pressure of 70 v. The layer of the copper line shall be separated by an insulation film to allow for the dissipation of the heat and, if necessary, may be connected to the fan specifications (voltage, direct flow, etc.)。
In addition, at the end of 220 v, a chained copper line of 1. 5 mm may continue to be used to connect 380 v (608 mm total) with the same subtotal. At this time, the air-borne voltage will be reduced to 63. 75 v, the “weak” slots will be reduced to 46. 875 v, the “middle” slots to 56. 25 v and the “strong” slots to 65. 625 v。
Ii. Small welder measurements
1. Advantages of small welders:
Small welders use electrical energy, convert electrical energy instantaneously to thermal energy, electricity is common, small welders are suitable to work in a dry environment and do not require too many requirements. The advantages of small size, simplicity of operation, ease of use, speed of use, strong welding, etc. Are widely used in a variety of fields, especially in the case of highly demanding manufactures, which can connect the same metal material (or possibly alien metals with different welding methods) permanently in an instant, after welding is thermally treated, with the same strength and sealing as the mother, which solves the problem of sealing and strength in the manufacture of stored gases and liquid containers。
2. Shortcomings of small welders:
A small welder produces a certain magnetic field around a welder in the course of its use, radiation is generated from the arc burning around it, there is infrared light in the arc light, light like ultraviolet light, and harmful substances such as metal vapour and dust, so that adequate protective measures must be taken. Welding is not suitable for the welding of high carbon steel, and as a result of welding welding processes such as metal crystallization and decomposition and oxidation, welding performance is poor, welding is easily fractured, creating heat and cold cracks. Low-carbon steel has good welding performance, but it has to be properly operated, and is cumbersome with regard to rust cleaning, and sometimes welding leads to defects such as slag cracks and gas holes bites, but operations should reduce the generation of defects。
Small welding mechanisms are simple and interested boys' shoes can be tried, so that not only can they exercise their skills, but a small welder can come out at will。
