The emergence of welding caters to the need for new technological methods in the development of metal art.

Art creation and craftsmanship methods are always inseparable. As an industrial technology, the emergence of welding caters to the need for new technological means in the development of metal art. On the other hand, the wonderful changes produced by metal under the action of welding heat also meet the demand of metal art for new artistic expression languages. In today's metal art creation, welding

It is being vigorously expressed as an artistic expression language. Metal welding art can be separated from traditional metal art in a branching manner as a relatively independent art form, because welding has artistic qualities. Welding can generate rich artistic expression language. Welding is usually carried out at high temperatures, and metals undergo many wonderful and rich changes at high temperatures. The metal base material will undergo color changes and thermal deformation (i.e. welding heat affected zone); After the welding wire melts, it will form some beautiful textures; And welding defects are often applied in welding art. Welding defects refer to the defects that occur in the welding joint during the welding process and do not meet the design or process requirements. Its main manifestations include welding cracks, porosity, undercutting, incomplete penetration, incomplete fusion, slag inclusion, weld bead, collapse, pits, burn through, inclusions, etc. This is a very interesting phenomenon: in today's metal art creation, the artistic quality of welding is usually reflected in some failed industrial welding operations, or hidden in some welding defects that industrial welding tries to avoid. Secondly, the language of welding art is.

A welded sculpture has rough welds exposed on the surface, and various irregular cutting marks have become the artist's beautiful artistic language. In many cases, due to the rough and rustic style pursued by welded sculptures, the corrosion and defects of the metal are often deliberately preserved according to the needs of the work. Therefore, in welded sculptures, a non carved and primitive beauty can often be felt.

The weld seam at the steel plate joint in the lower part of the sculpture is very thick. From the perspective of the firmness of the welding process, this is obviously not only due to considerations of the solidity of the sculpture. In this sculpture, the twisted weld seams in the lower part have become an important factor in the overall aesthetic of the sculpture and have become a small part of it. From the overall perspective of the sculpture, whether it is the text design in the upper part or the texture treatment in the lower part, there are twisted welding marks everywhere, and the entire work achieves a unified visual language. The method of manual plasma cutting utilizes the heat generated by the current during cutting to create a heat affected zone at the cutting edge, thus "dyeing" the bright white stainless steel with a slightly gradient color. At the same time, by adjusting the welding specifications, the strong airflow sprayed by the cutting gun will "blow" a randomly formed texture around the cutting edge at the moment when the steel plate melts. The formation process of this random effect has a certain degree of randomness, but it is also an inevitable phenomenon under certain welding specifications. From a size perspective, larger welding art wall decorations can be welded using semi-automatic CO2 gas shielded welding, while smaller ones can be welded using manual tungsten inert gas welding.

If a wall decoration work is regarded as a painting, the processing of points, lines, surfaces, black, white, gray, and even colors in the picture can be achieved through welding. Various types and materials of metal wires, using different welding processes, will appear in different forms on the screen. Different metals have different colors, such as stainless steel's bright silver, aluminum's sub silver, carbon steel's jet black, titanium steel, bronze, purple copper, brass, and as for steel, different steels will undergo different color changes when heated at high temperatures, that is, different welding heat affected zones. In addition, cutting is also one of the methods for creating welding art wall decorations, which can be combined with welding or used alone, depending on the creator's creative intention and mastery of the process and effect. The richness of the changes can be imagined when these methods are combined.

A holistic approach.

Causes of fire and explosion accidents

During welding and cutting operations, especially gas cutting, the use of compressed air or oxygen jets can cause sparks, molten beads, and iron slag to splash everywhere (larger molten beads and iron slag can splash up to 5m away from the operating point). When flammable, explosive materials or gases are present in the working environment, fire and explosion accidents may occur.

⑵ During high-altitude welding and cutting operations, flammable and explosive materials within the range of Mars were not cleaned thoroughly. The operators threw welding rod heads around during the work process and did not carefully check whether there were any sparks left after the operation was completed.

During the process of gas welding and gas cutting, the acetylene generator was not placed according to the prescribed requirements, and the safety devices of the welding (cutting) torch, rubber pipeline, and acetylene generator were not inspected as required before work.

There are deficiencies in the formulation of gas cylinders, deficiencies in the storage, filling, transportation, and use of gas cylinders, and violations of safety operating procedures.

There are defects in the development and installation of acetylene, oxygen and other pipelines, which have not been detected and rectified in a timely manner during use.

(6) Failure to take appropriate measures as required when welding fuel containers and pipelines. During the implementation of replacement welding repair, the replacement is not complete, and insufficient pressure during the implementation of non replacement welding repair with pressure leads to the introduction of external flames.

preventive measures

During welding and cutting operations, all flammable and explosive materials within a 10 meter radius of the work environment should be cleaned up. Attention should be paid to checking whether there are flammable liquids and gases in the trenches and sewers of the work environment, as well as whether there is a possibility of leakage of flammable and explosive materials into the trenches and sewers, in order to avoid accidents caused by welding slag and metal sparks.

⑵ During high-altitude welding and cutting, it is prohibited to litter welding rod heads. The area below the welding and cutting operation should be isolated. After the operation is completed, a careful and meticulous inspection should be carried out to confirm that there are no fire hazards before leaving the site.

Gas cylinders that comply with relevant national standards and regulations should be used, and safety operating procedures should be strictly followed during the storage, transportation, and use of gas cylinders.

Pipelines transporting combustible gases and combustion assisting gases should be installed, used, and managed in accordance with regulations, and specialized safety technical training should be provided to operators and inspectors.

When welding fuel containers and pipelines, the welding method should be determined based on the actual situation. When implementing the displacement method, the displacement should be minimized, and the presence of flammable substances should be strictly controlled during work. When implementing the pressurized non displacement method, a certain voltage should be maintained as required. The oxygen content should be strictly controlled during work. We need to strengthen testing, pay attention to supervision, and have safety organizational measures.

Summary: As an industrial technology, the emergence of welding caters to the need for new technological means in the development of metal art. On the other hand, the unique and wonderful changes produced by metal under the action of welding heat also meet the demand of metal art for new artistic expression languages.
