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.

可以确定的原则就是，人类探求真理的步伐不会停息，在不断自我否定与自我完善中，现代变形金刚模型艺术必将走向一个新的开端。

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.

大型变形金刚承袭了不锈钢的众多的优点，与传统的雕塑和石雕作品相比，大型变形金刚模型有着鲜明的特征，大型变形金刚不爱生锈，容易大型变形金刚放的过程中不需要花很多的时间进行保养，同时也不用担心大型变形金刚在摆放的过程中，会因为大气、雨水而发生生锈的现象。大型变形金刚模型的抗风能力是很强的，经久耐用。大型变形金刚本身的颜色银白色，具有光泽大型变形金刚如果有特殊的要求也可以加工成其他的颜色。

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.

大型变形金刚存在时间并不长，但是应用的范围已经非常的广了，这其中包含了许多的模型家和艺术家的努力，为大型变形金刚的发展提供了重要的支持。大型变形金刚的发展大型变形金刚很远的路程在这路上，需要每个模型家不断的努力，不断的推广，终保证大型变形金刚能够有更广阔的发展前景。

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.

变形金刚模型是指以金属为物质材料的模型作品，金属材料的应用是人类文明发展进程中一个极为重要标志。在模型领域中，金属材料的使用，应该上溯到新石器时代后期，铁器、铜器、青铜器的出现，标志着人类熟练掌握了冶炼铸造技术。金属材料，因为易加工，可以长久保存等特点，广泛应用于器皿、等方面，其间不乏从体量到工艺都堪称模型作品的金属制品，既有实用价值，更有很强的审美价值。现代，新的技工工艺和金属种类的出现，使金属材料在模型方面应用更加广泛，金属材料在模型领域使用率占地位，常见的性模型、纪念性大型变形金刚模型多以金属为材料。

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.

金属种类繁多，各有不同的物理特性，可以切割、焊接、铸造、锻造，表面处理可以打磨、抛光、腐蚀上锈，以不同的加工工艺制作变形金刚模型作品表现多种材质之美和意境。金属材料具有迷人的材质美感，模型家的艺术思维、创作情感，在金属材质美的辉映下得到彰显，既有稳定沉着的材质感，又蕴含深刻的内在意蕴，这也是模型家更多选用金属材质的一个重要原因。经过漫长发展历程，艺术家对金属材质的特性和艺术表现力积淀了深厚经验，创作了形式新颖、门类多样的现代表现型金属变形金刚模型。

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.
