The large-scale transformer model is not made of a steel plate. It is composed of several waste automobile parts. In the process of combination, the problem of welding is designed. Now there are three commonly used welding methods. The method of combining the workpiece by heating or pressurizing, or both, or possibly filling material. There are usually fusion welding, pressure welding and brazing. A processing method that enables the workpiece to achieve atomic bonding and non detachable connection by heating and pressurization. Including fusion welding, pressure welding, brazing, etc. A method for connecting metal structural members by using the mutual penetration of metal molecules between connectors to form a whole at high temperature.

可以確定的原則就是，人類探求真理的步伐不會停息，在不斷自我否定與自我完善中，現代變形金剛模型藝術必將走向一個新的開端。

The only certain principle is that the pace of human exploration of truth will not stop. In the continuous self denial and self-improvement, the modern transformer model art will move towards a new beginning.

大型變形金剛承襲了不銹鋼的眾多的優點，與傳統的雕塑和石雕作品相比，大型變形金剛模型有著鮮明的特征，大型變形金剛不愛生銹，容易大型變形金剛放的過程中不需要花很多的時間進行保養，同時也不用擔心大型變形金剛在擺放的過程中，會因為大氣、雨水而發生生銹的現象。大型變形金剛模型的抗風能力是很強的，經久耐用。大型變形金剛本身的顏色銀白色，具有光澤大型變形金剛如果有特殊的要求也可以加工成其他的顏色。

Large transformers inherit many advantages of stainless steel. Compared with traditional sculptures and stone carvings, large transformers model has distinct characteristics. Large transformers do not love rust, and it is easy to put large transformers. It does not need to spend a lot of time for maintenance. At the same time, there is no need to worry that large transformers will be damaged by the atmosphere Rust occurs due to rain. The large transformer model has strong wind resistance and durability. The color of large transformers is silver white and shiny. Large transformers can also be processed into other colors if they have special requirements.

大型變形金剛存在時間并不長，但是應用的范圍已經非常的廣了，這其中包含了許多的模型家和藝術家的努力，為大型變形金剛的發展提供了重要的支持。大型變形金剛的發展大型變形金剛很遠的路程在這路上，需要每個模型家不斷的努力，不斷的推廣，終保證大型變形金剛能夠有更廣闊的發展前景。

Large transformers haven't existed for a long time, but the scope of application has been very wide, which includes the efforts of many modelers and artists, which provides important support for the development of large transformers. The development of large transformers is a long way. On this road, every modeler needs continuous efforts and promotion to ensure that large transformers can have broader development prospects.

變形金剛模型是指以金屬為物質材料的模型作品，金屬材料的應用是人類文明發展進程中一個極為重要標志。在模型領域中，金屬材料的使用，應該上溯到新石器時代后期，鐵器、銅器、青銅器的出現，標志著人類熟練掌握了冶煉鑄造技術。金屬材料，因為易加工，可以長久保存等特點，廣泛應用于器皿、等方面，其間不乏從體量到工藝都堪稱模型作品的金屬制品，既有實用價值，更有很強的審美價值。現代，新的技工工藝和金屬種類的出現，使金屬材料在模型方面應用更加廣泛，金屬材料在模型領域使用率占地位，常見的性模型、紀念性大型變形金剛模型多以金屬為材料。

Transformer model is a model work with metal as material. The application of metal material is a very important symbol in the development of human civilization. In the model field, the use of metal materials should be traced back to the late Neolithic age. The emergence of iron, bronze and bronze marks that human beings have mastered the smelting and casting technology. Metal materials are widely used in utensils and weapons because they are easy to process and can be preserved for a long time. There are many metal products that can be called model works from volume to technology, which have both practical value and strong aesthetic value. In modern times, with the emergence of new craftsmanship and metal types, metal materials are more widely used in models. Metal materials occupy an absolute position in the field of models. Most of the common permanent models and commemorative large transformer models are made of metal.

金屬種類繁多，各有不同的物理特性，可以切割、焊接、鑄造、鍛造，表面處理可以打磨、拋光、腐蝕上銹，以不同的加工工藝制作變形金剛模型作品表現多種材質之美和意境。金屬材料具有迷人的材質美感，模型家的藝術思維、創作情感，在金屬材質美的輝映下得到彰顯，既有穩定沉著的材質感，又蘊含深刻的內在意蘊，這也是模型家更多選用金屬材質的一個重要原因。經過漫長發展歷程，藝術家對金屬材質的特性和藝術表現力積淀了深厚經驗，創作了形式新穎、門類多樣的現代表現型金屬變形金剛模型。

There are many kinds of metals with different physical characteristics. They can be cut, welded, cast and forged. The surface treatment can be polished, polished, corroded and rusted. Transformer model works are made with different processing technologies to show the beauty and artistic conception of a variety of materials. Metal materials have charming aesthetic feeling of materials. The artistic thinking and creative emotion of modelers are highlighted under the beauty of metal materials. They not only have a stable and calm sense of materials, but also contain profound internal meaning, which is also an important reason why modelers choose metal materials more. After a long development process, artists have accumulated profound experience in the characteristics of metal materials and artistic expression, and created modern expressive metal transformer models with novel forms and various categories.
