The welding process consists of heating the base materials until a fusion process starts and the samples will be welded.
The phenomenon represents a dielectric relaxation of the dipoles inside the base materials.
The tungsten electrode should be placed just above the base materials to be joined
Materials and Methods As base materials were used, in experimental procedure, copper wires having diameter equal with 0.65 mm.

The top-seeded melt-growth (TSMG) process has been widely employed to produce single grain materials, allowing the batch production of RE-123 materials [7].
IG-processed materials show uniform 211 secondary phase particles in the Y-123 matrix.
Former studies [7-11] clarified that the IG-processed YBa2Cu3Oy “Y-123” materials exhibit higher Jc values than those of melt-textured Y-123 materials.
For magnetization measurements, the specimens were cut from bulk materials at 2 mm below the seed crystal.

Introduction Housing is the people's basic living material, and the housing problem is a significant social problem.
Obvious changes of many wall materials have taken place in developed countries.
For example, the proportion of clay brick in the wall materials has dropped to 37.9% at the former Soviet union in the early 80s.
The proportion of new building materials are generally accounts for 60-90% in these countries.

The fundamental formula of the mechanics of materials is derived under the equal-section assumption.
This local stress is critical for the mechanical properties of the materials, especially for the members which are manufactured by the brittle materials[5], This stress change has a great impact on the safety of aerospace vehicles.
