1. Introduction

Welding is a reliable and efficient metal-joining process

widely used in industry. Plates of different thickness are

used in industry and thick plates are normally joined by

multipass welding. When analyzing multipass welding

one also needs to model the addition of (new) filler material

as new weld passes are deposited and the geometry of the

weld joint is being built-up. This makes it difficult to model

the multipass welding with finite element method (FEM).

Due to the intense concentration of heat in the heat source

of welding, the regions near the weld line undergo severe

thermal cycles, thereby maybe generating weld solidification

cracks in the weldment. Therefore, modeling weld

solidification cracks have been a major topic in welding a

variety of engineering alloys.

    Welding is a reliable and efficient metal-joining process widely used in industry.

    焊接是一個廣泛應用在工業上可靠又有效率的金屬連接過程。

    Plates of different thickness are used in industry and thick plates are normally joined by multipass welding. When analyzing multipass welding one also needs to model the addition of (new) filler material as new weld passes are deposited and the geometry of the weld joint is being built-up.

    工業上使用不同厚度的金屬板,並且厚的金屬板一般是以多次焊接來連接。因為採用新的焊接方式且焊接點的位置正被重組出來,所以在分析多次焊接時,也需要對新加入的填充材料進行型塑,

    This makes it difficult to model the multipass welding with finite element method (FEM).

    這使得以有限原素法(FEM)來塑造多次焊接變得困難。

    Due to the intense concentration of heat in the heat source of welding, the regions near the weld line undergo severe thermal cycles, thereby maybe generating weld solidification cracks in the weldment.

    由於焊接熱源的熱度密集集中,焊線附近的區域處於嚴重的熱循環,因此,在焊接時,凝固的焊點可能會產生裂痕。

    Therefore, modeling weld solidification cracks have been a major topic in welding a variety of engineering alloys.

    因此,在焊接各種工業合金時,塑造焊點的裂痕一直是一個主要的議題。
