What is process testing? What does the construction site process test mean?

Process testing refers to the welding process.

First, the welding technician formulates the plan, then welds the test plate, and finally conducts various tests to evaluate the rationality and correctness of the process plan.

There are many types of energy** in modern welding, including gas flames, arcs, lasers, electron beams, friction and ultrasonics. In addition to being used in factories, welding can also be performed in a variety of environments, such as in the field, underwater, and in space. Welding can be dangerous to the operator wherever it is, so proper precautions must be taken when performing welding.

Possible injuries to the human body caused by welding include burns.

Electric shock, vision impairment, inhalation of toxic gases, excessive UV exposure, etc.

To be precise, the process test is a test carried out to examine the feasibility of the process method, the process parameters or the machinability of the material.

For example, the steel bar welding process test: the climatic conditions, welding machine parameters, current size, welding rod model, whether the rod is preheated, and the welding effect (whether the weld strength meets the requirements) should be recorded. According to the results of the process test, the work instructions that can guide the formal construction are summarized.

For example, the filling of the subgrade test section: the thickness of the soil loosening, the moisture content of the filler, the compaction thickness, the tonnage of the rolling machine, the travel speed, the number of rolling times, etc., should be recorded. According to the results of the process test, the work instructions that can guide the formal construction are summarized.

The construction site process test is a test carried out under natural conditions outside the laboratory in order to determine the feasibility, stability and applicability of a certain construction process during the construction of the building, as well as to optimize and improve it according to the actual situation. Its purpose is to ensure the quality of construction, improve construction efficiency and reduce construction risks.

The construction site process test generally performs the following steps:

1.Determine the test items: Determine the corresponding test items for the technical problems that need to be verified in the construction process.

2.Preparation of test plan: determine the process plan of the test, the test model or the construction method of the model, the test stage and the test method, and prepare a detailed test plan.

3.Prepare test materials: Prepare test materials according to the requirements of the test plan, such as: concrete, steel bars, bricks, etc.

4.Conduct the test: The test is carried out according to the test plan at the construction site, and the slag macro is recorded and analyzed.

5.Result evaluation: evaluate and analyze the test results, summarize experience, and put forward optimization and improvement plans.

6.Comprehensive promotion: summarize the results obtained from the test and promote the successful experience to other construction projects.

It is of great practical significance to effectively solve the technical problems in the construction process, ensure the quality of the project, improve the construction efficiency and reduce the construction risk through the construction site process test.

Hello, the construction site process test refers to the test of the relevant project in the construction process in order to verify whether the materials and equipment meet the specifications, whether the construction process meets the requirements after the combustion and grinding, and whether the construction quality meets certain standards. It includes the evaluation test of materials and equipment, the detection and determination of the physical properties, mechanical properties and other properties of the construction process, and the inspection and determination of construction quality. Secondly, the construction site cruise ship process test refers to the experimental testing carried out in the construction process to ensure the construction quality and determine the accuracy of the materials, tools and technologies used in the construction process.

The test items mainly include the determination of material compressive strength, parsley, material conductivity, welding technical index test, concrete climate adaptability test, concrete compressive strength and flexural strength determination, etc. These tests can not only ensure that the construction quality meets the requirements, but also grasp the construction quality trend so that corresponding improvement measures can be made.

Take earthwork as an example, the experiment is the density detection of earthwork backfill, on-site sampling, in order to prevent future settlement This is a very intuitive reaction to the detection of the construction process, in other words, the reaction of earthwork filling is whether to use a tamper or a key roller for tamping or compaction, steel bar welding is specially done welding closed such as joints Go to the laboratory of the competent department for a lapa experiment to see if the strength requirements required for design are met.

The construction site process test refers to the inspection of construction technology and construction quality carried out at the construction site, such as concrete compressive strength test, concrete tensile strength test, concrete flexural strength test, concrete freezing test, etc., as well as tensile strength, compressive strength, bending and punching strength, flexural strength, flexural strength, freezing resistance test of soil, mortar, concrete, wood, steel bar and other materials. The construction site process test can effectively guarantee the construction quality, improve the construction efficiency, reduce the loss of the construction process, ensure the stability and reliability of the construction quality, and ensure the normal completion of the construction project.

1. The purpose of the test is different.

The production test is carried out to verify the feasibility of mass production and whether the yield is up to standard; The process test only considers the process feasibility, and does not consider the impact of mass production.

2. The test method is different.

The process test is often based on the raw materials and the process as the main reference standard, if the process is qualified, and the raw materials are correct, then the process can be successfully completed; The production experiment is carried out with the land occupation, batch size, and compliance rate as the standard, in other words, to verify whether the experiment can be carried out in large quantities.

For example, if a part cannot be assembled to the board with a machine and can be welded manually, the process test is to evaluate the feasibility of hand welding and whether it can be assembled. The productivity test should consider the efficiency of mass production and whether the yield of welding is up to standard.
