Anonymous users2024-02-15The wire feed position is incorrect, and the end of the wire stays in the area of high arc space temperature to form a small ball. The correct operation is to let the temperature of the weld pool melt the wire, not let the arc melt the wire, and send the wire to the weld pool.

Anonymous users2024-02-14The protective gas flow is too large and too small, usually the gas flow is too small, generally not more than 10. It is also best not to be less than 2, it depends on the thickness of the product that is welded randomly, and the speed to adjust the current and so on.
The welding wire is fed through the wire wheel, and the contact tip conducts electricity, which generates an arc between the base metal and the welding wire, melts the welding wire and the base metal, and uses inert gas argon to protect the arc and molten metal for welding.
The arc combustion of argon arc welding is stable, the heat is concentrated, the arc column temperature is high, the welding production efficiency is high, the heat affected zone is narrow, and the weldment stress, deformation and crack tendency of the weldment are small.

Anonymous users2024-02-12The cause of blistering in TIG welding is:
First, the gas flow is small or it is not rough.
Second, the cleanliness of the board is not reached.
The third is that the welder did not follow the requirements of the specification when the operation was a big sale. Trapped imitation town.

Anonymous users2024-02-11Hello, it is a pleasure to serve you and give you the following answers: Causes of the problem:1
Improper welding parameters: Improper welding parameters of TIG welding, such as current, voltage, welding speed, etc., will lead to welding failure, resulting in deformation and brittleness of the welding part. 2.
Improper welding technology: Improper welding technology of argon arc welding, such as too long welding time and improper welding depth, will also lead to welding failure, resulting in deformation and brittleness of the welding part. 3.
Improper welding materials: Improper welding materials for argon arc welding, such as the type and quality of welding consumables, will also lead to welding failure, resulting in deformation and brittleness of the welding part. Workaround and Procedure Steps:
1.Check the welding parameters: check the welding parameters of TIG welding, such as current, voltage, welding speed, etc., to ensure that the parameters are correct.
2.Check the welding technology: Check the welding technology of TIG welding, such as welding time, welding depth, etc., to ensure that the technology is correct.
3.Check the welding materials: check the welding materials of TIG welding, such as the type and quality of the welding and rolling materials, to ensure that the materials are correct.
4.Check the welding position: Check the welding position of TIG welding to make sure the position is correct.
Personal Tips:1In argon arc welding, it is necessary to ensure that the welding parameters, welding technology, welding materials and welding position are correct to ensure the welding quality.
2.In TIG welding, it is necessary to pay attention to controlling the welding time to avoid the welding time being too long, which will lead to welding failure. 3.
In argon arc welding, it is necessary to pay attention to controlling the welding depth to avoid it.

Due to the strong affinity between aluminum and oxygen, oxidation can occur at room temperature to form aluminum oxide film, the melting point of aluminum is only 660, and the melting point of aluminum oxide is as high as 2050, so it is necessary to use AC tungsten argon arc welding machine, or DC tungsten argon arc welding machine reverse polarity, use cathodic crushing function to break the oxide film, cathodic crushing process will cause spherical burning loss to the tungsten pole.
When welding aluminum, tungsten electrode does not need to be regrinded. Direct welding until the tungsten extreme forms a spherical shape, which can be used for normal welding operations.

Anonymous users2024-02-09There may be a cause of the collapse.
1. The weld is not clean. There are oil stains, moisture, etc.
2. The shielding gas is impure.
3. The end of the welding wire is exposed to air.
Patches. 1. Remove the air hole with an angle to the machine pants.
2. Clean the surface of the weld to be welded. (can be cleaned with acetone if necessary) 3 argon used.
4. When welding, the end of the welding wire should always be protected by inert gas.
Trust you, it will be soldered.
The cactus ball has dark spots on it, probably because it is infected with anthrax. The disease begins with water-staining and small light brown spots, which later turn brown, grayish-brown, grayish-white to black-brown, round or nearly circular in shape, and are between centimeters or larger in diameter. Sometimes the lesions are wet rot and concave, with slightly raised edges. >>>More
The presence of such dandruff at the hilum or near the bun is considered to be a manifestation of seborrheic dermatitis. Seborrheic dermatitis is a chronic inflammatory disease that occurs in the seborrhea site, and its ** is not very clear at present, and it is believed that it may be related to genetics and sebum metabolism. Its main typical clinical manifestations are erythematous papules or patches and plaques on the head and face, chest and back or perineum, accompanied by some greasy scales or crusts, usually accompanied by varying degrees of itching. >>>More
There are many reasons, but the main ones are as follows: first, the varieties of sweet potatoes are not selected well, and they should be selected for fertilizer tolerance, drought resistance, early tubing, and potato nuggets expand quickly and for a long time; Second, the choice of soil is not suitable, sweet potatoes are not very high requirements for soil acidity and alkalinity, but the soil is required to be soft, moisturizing and water retaining good, more agricultural fertilizer should be applied to poorer ridge land, and sweet potatoes should be rotated in crop rotation, and they will have to change the land next year; Third, there is no reasonable fertilization. Fertilization should be based on the fertilization principle of farmhouse fertilizer, supplemented by chemical fertilizer, base fertilizer, and top dressing; Fourth, the management is not in place, and it is better to plant reasonably densely, no more than 4 plants per square meter, so that sweet potatoes have enough light. >>>More

Purple lips indicate that you have insufficient blood supply during swimming, and the lack of oxygen is causing congestion instead of the above, so you have to be careful that you may have chest tightness and dizziness during swimming, causing accidents, resulting in many reasons for insufficient blood supply, and it is recommended that you go to the hospital to have your heart checked.
