IWOTE'11

International Workshop on Thermal Forming and  Welding Distortion

April 06 - 07, 2011

Hotel Munte, Bremen, Germany

Introduction

Nowadays, welding is a widespread and highly developed joining method. More than 120 automatic and manually operated processes are applicable. As an unwanted side effect, heating and melting induce thermal strains and alter certain material properties. This leads to distortions and high residual stresses which  should obviously be kept to a minimum. Therefore, various strategies are being developed in order to minimize distortions, materials are investigated and mechanical as well as thermal boundary conditions are researched. In contrast to welding, the aim of thermal forming is to deliberately use thermal strains to generate predicted shapes. In thermal forming well-defined heat sources offer a reproducible heat input into a highly localized area. The different forming mechanisms are specified and further investigated. Furthermore, thermal forming can overcome limits of the accessibility and avoid disadvantages of mechanical forming like the spring back effect.

The intention of the IWOTE'11 is to combine knowledge and experience in the fields of thermal forming and welding. Current shared questions concerning e.g. a quasi-static process behaviour, the analysis of large structures, size effects, the influence of the material strength and hardening behaviour and fast analysis methods will be discussed.

Objectives

The workshop is intended to promote the exchange of  experience at international level and foster the dialogue between science and industry, related to the shape changing phenomena in thermal forming and welding.
