The weld induced deformation is considered as the major stumbling block that can affect the dimensional accuracy.
This type of structural steels has been extensively used in many applications, combining good welding properties with guaranteed strength.
The mechanical and thermal properties are tabulated in Table 3.
Physical properties of St52.
In addition, physical properties of materials, chemical composition of materials, geometry and thickness might be the factors that contributed to the deviated results.

The band saw steel must present a good balance between strength, toughness and materials elasticity in the weld joint, respectively in the heat affected zone (HAZ).
Those areas are affected by the heat welding cycle that is changing the material microstructure and consequently the overall mechanical properties of the saw blade.
The strip steel dimensions are 38 x 1.14 mm, the chemical composition and mechanical properties being presented in the Table 1 [2].
Steel strip chemical composition and mechanical properties [2].
Both non-metallic inclusions or carbide precipitates at the grain boundary can negatively affect the fatigue strength of the saw blade.

According to the literature the paper lists five different kinds of loads affecting the stability analysis of pumper and discusses the verification methods and the principles of judgments.
Affecting loads of the stability.
The reliability of the ladder structure is to the most critical factors in firefighting and rescue work.
Conclusions This paper analyzed the stability of the self-designed pumper, getting five types of loads affecting the stability, and discussed the verification methods and the principles of judgments.
In addition, other properties of products still need further experimental verification after the completion of the trial production.

They focused on the effects of the following factors on the FBAM: belt transport speed, angle between rollers, dimension of rollers, geometric and material characters of belt[12].
These defects were the random factors of the measurement.
Actually this property can be proved theoretically.
This property was also proved theoretically.

Concrete-polymer composites (C-PC) have excellent mechanical and durability properties.
Concluded that the proper mix design outstanding increase the physical and mechanical properties of the cured composite.
In addition to the mechanical properties, other properties such as thermal conductivity, shrinkage, creep and fire protection are beginning to make a great relevance.
PCM with EVA 5% (P/C) and polyacrylic ester (PAE) series in the range of 5-20% showed good mechanical properties in the range of 200-400 oC.
There are many factors affecting the bond quality.

Fig. 1 Tensile curves of low carbon steel There are three external factors affecting the yield stress of materials: temperature, strain rate and stress state.
Instability in the torque in coiling process will lead to inaccuracy in tracking torque, affecting constant tension control.
Owing to temperature directly affecting strip hardness, the coiling torques can be compensated according to the variable temperature [7].
It includes a gain factor and the bending torque.

It is considered that the formation of δ hydrides, lattice defects and alloying element diffusion are the major factors leading to the microhardness change.
Thermo Hydrogen Treatment (THT), or the use of hydrogen as a temporary alloying element, can strongly modify the microstructures and enhance the mechanical properties of titanium alloys [2-4].
However, the influences of hydrogenation on mechanical properties especially on microhardness has been less investigated.
(3) It is considered that the formation of δ hydrides, lattice defects and alloying element diffusion are the major factors leading to α and β phases microhardness change.

CBR Test There are many factors affecting the bearing ratio.
The final result is the structural framework of soil becomes loose, expressed as obvious decrease of soil strength on mechanical property.
The internal factors affecting the soil expansion and deformation are mainly: clay minerals and their chemical composition, clay particle content, void ratio, water content, microstructure and structural strength of soil, etc[9-10].

The variation in properties across the weld can be attributed to several factors, mainly to residual stresses just after welding.
On the other hand, other factors can contribuate to this hardening like grain size, phase composition, metallic inclusions.
